Corrupted Files Update - CANT LAUNCH GAME

I’ve been trying to play this game since yesterday and I cannot fix this issue.
I have reinstalled the game on different drivers, verified game files, restarted, but it still continues to tell me the files are corrupted.

Hi @bunnri welcome to Lost Ark forums, I hope you are having a wonderful day.

Can you confirm if you are still having this issue?

Just in case you are still have the issue I’m going to provide you some troubleshooting steps:

First lets try with the EasyAntiCheat program:

  1. Open Lost Ark in your Steam Library.
  2. Right click on Lost Ark’s list title and then Go to Settings < Manage < Browse Local Files.
  3. Open the EasyAntiCheat folder.
  4. Run as administrator EasyAntiCheat_Setup executable file.
  5. Make sure in the drop-down within EasyAntiCheat Service Setup Lost Ark is the selected game.
  6. Press Repair Service.
  7. After this process verify Steam Integrity Check files: Steam Support :: Verify Integrity of Game Files (Steam Support :: Verify Integrity of Game Files ).
  8. Re-launch Lost Ark.
