It seems like i have the same Error that the guy from this thread had: https://forum.plutonium.pw/topic/792/can-t-start-the-game/2?_=1587465695114
However my game files are valid. I have repaired them with steam and i am able to start the normal multiplayer.
I already reinstalled the game and deleted the config file from %localappdata%/plutonium and it still shows me the same error any idea what I am doing wrong?
