Solution: Try moving your entire Steam or game folder to C:\Program Files (x86) if it is currently in a non-standard directory. 4. Clear Temporary Cache

Corrupted shader or temporary data can also lead to file read errors. Press Windows + R, type %temp%, and press Enter.

Delete the contents of this folder (skip files currently in use). Restart your PC and relaunch the game. 5. Final Resort: Reinstall

If the error persists after verifying files, a clean installation is often the only way to ensure all .ff (FastFile) assets are correctly localized and registered by the game engine.
