How to Fix Aion 2 Not Loading and Freezing Issues (2026 Guide)

I’ll be honest — I went into the Aion 2 Launch Scale Test expecting flying battles over Atreia, not a staring contest with a loading bar. And judging by my Discord and half of Reddit right now, I wasn’t alone. Between infinite loading screens, random freezes on the character select screen, and that lovely little “0xE0000015” fatal error slapping me back to desktop, it’s clear NCSOFT’s UE5 monster is putting a real strain on a lot of rigs — and on a lot of patience.

So instead of doom-scrolling forum threads for another hour, I sat down, tried basically everything the community has thrown at this problem, and organized it into an order that actually makes sense. No fluff, no “just restart your PC” nonsense as a first step. Let’s get you back in the game.

Why Is This Even Happening?

Before we start clicking things, it helps to understand why Aion 2 is misbehaving. From what I’ve pieced together (and from what a lot of tech-savvy players have confirmed independently), the freezing and loading issues generally come down to four culprits:

• Corrupted or incomplete game files left over from patching or a rocky install
• Server-side handshake delays, especially during instance transitions or character loading, made worse by rough routing to NCSOFT’s servers
• Outdated system dependencies (Visual C++, DirectX) that a next-gen UE5 title simply won’t tolerate
• Background software conflicts — overlays and monitoring tools that try to hook into the rendering pipeline and choke it

Once you know which bucket your problem falls into, the fix gets a lot less mysterious. Here’s my full breakdown.

1. Start With the Boring Stuff: Verify Your Files

I know, I know — “have you tried verifying your files” is the tech support equivalent of “have you tried turning it off and on again.” But it genuinely resolves a huge chunk of freeze-on-loading-screen complaints, because a single mangled texture file can stall the entire engine before it even gets to the main menu.

On the PURPLE launcher:

1. Fully quit Aion 2 and the PURPLE launcher itself.
2. Pop open Task Manager (Ctrl + Shift + Esc) and kill any stray PURPLE/NCSOFT processes still lurking.
3. Relaunch PURPLE, head into App Settings → App Data/Client Settings.
4. Hit Clear Launcher Cache.
5. Find the File Scan/Repair tool under the Aion 2 tab and run it.

On Steam:

1. Open your Library, right-click Aion 2 → Properties.
2. Go to Installed Files.
3. Click Verify Integrity of Game Files and let it do its thing.

Takes five minutes. Saves you an hour of guessing.

2. The Loading Loop Is Probably a Handshake Problem, Not Your PC

This is the one that gets people the most, because it feels like your computer is broken when really it’s a conversation between your client and the server that never finished. Aion 2 leans hard on regional routing and separate instance servers, so if your connection to those servers hiccups, you get stuck staring at a spinning icon forever — usually right after character select or when zoning into a dungeon.

Here’s what’s actually worked for people:

If you’re going the booster route, don’t just optimize the game executable — optimize the launcher too (PURPLE or Steam), since the initial handshake often happens before Aion2.exe even fully loads. A few people in my circle said flipping the routing node from “Manual” to “Automatic” fixed it instantly, so that’s worth a shot before you go digging through advanced settings.

3. Missing Redistributables Will Absolutely Wreck You

If your game is dying on a black screen or throwing that 0xE0000015 error, don’t overthink it — this is almost always a missing or corrupted dependency, not some deep engine bug.

• Grab the latest Visual C++ Redistributable (x64) straight from Microsoft’s site
• Run it — if it detects an old install, choose Repair, not just Install
• Double-check your DirectX 12 runtime is current
• Restart before relaunching — this step gets skipped constantly and it matters, since Windows needs to remap the repaired DLLs

This one’s a five-minute fix that solves a surprising number of “why does my game just die” tickets.

4. Kill Your Overlays. All Of Them.

Unreal Engine 5 games have a well-earned reputation for hating anything that tries to hook into the rendering pipeline mid-session, and Aion 2 is no exception. If you’re the type to run six background apps while gaming (no judgment, I do too), this is probably your issue.

Shut down before launching:

• Discord overlay
• GeForce Experience / Nvidia app overlay
• AMD Adrenalin overlay
• Xbox Game Bar
• MSI Afterburner, Process Lasso, ParkControl (these three specifically have been called out repeatedly as freeze triggers)

If you’re not sure what’s causing it, do a Clean Boot: Win + R → msconfig → Services tab → check “Hide all Microsoft services” → Disable all → restart and test. It’s tedious, but it’s the most reliable way to isolate a rogue background process.

5. Your Virtual Memory Might Be the Bottleneck

Running 16GB of RAM? That’s technically the floor for a UE5 MMORPG doing faction warfare with a hundred bodies on screen, and when physical memory maxes out, Windows needs somewhere to overflow to. If your paging file isn’t configured generously, you’ll crash instead.

Quick manual setup:

1. Control Panel → System → Advanced system settings
2. Performance section → Settings → Advanced tab → Change (under Virtual Memory)
3. Uncheck “Automatically manage paging file size”
4. Pick your SSD (ideally the one Aion 2 is installed on)
5. Set Initial size = your RAM in MB (16GB → 16384)
6. Set Maximum size = 1.5x that (16GB → 24576)
7. Set, OK, apply, restart

Not glamorous, but it genuinely reduces crash-to-desktop frequency under heavy load.

6. Nuke Your GPU Drivers and Start Fresh

If your freezes line up with heavy visual moments — water rendering, DLSS kicking in, big teleport loads — old driver fragments are a likely suspect. A basic “update driver” click often isn’t enough because it doesn’t clear out corrupted remnants underneath.

• Download Display Driver Uninstaller (DDU)
• Boot into Safe Mode, run DDU to fully wipe your current driver
• Reboot normally, install the latest stable driver from NVIDIA/AMD/Intel directly
• In-game, if freezes persist during specific moments, try disabling DLSS or dropping from Quality to Performance preset — shadows, volumetric clouds, and water ambient settings are the heaviest hitters

7. When All Else Fails: Clean Reinstall

If you’ve been through everything above and Aion 2 still won’t cooperate, it’s time for the nuclear option:

• Uninstall completely through Steam or PURPLE
• Manually check C:\Program Files (x86) or your Steamapps folder for leftover Aion 2 folders and cache — delete them
• Restart your PC, relaunch your launcher as Administrator, and pull a completely fresh copy

One Last Thing Worth Remembering

Not every freeze is on you. During a global scale test or early access window, some infinite loading loops are just structural bugs or server-side hiccups on NCSOFT’s end, and no amount of local tinkering will fix a server outage. If your feed is suddenly flooded with the exact same complaint from dozens of players at once, that’s your cue — stop troubleshooting, check official channels, and wait for a hotfix or maintenance window instead of burning another hour on your own system.

Run through this list in order, and odds are you’ll be back in Atreia well before the servers even need to intervene. Good luck out there — see you in the skies.
