I have Eternal Crusade through steam.
I get the error message that
[An error occurred while updating Warhammer 40,000: Eternal Crusade (content file locked):
C:\.....\Steam\steamapps\common\Warhammer 40,000 - Eternal Crusade\EternalCrusade\Binaries\Win64\EternalCrusadeClient.exe" ]
I have tried updating the game, verifying the games integrity and reinstalling however the file will still not launch, when I go to that location the file is not there and when I re-install it is missing.
