@mazornoob Changing the directory worked, thanks. I'm somewhat annoyed that it was just that easy, but thank you nonetheless!

So, basically, I've followed all of the steps listed here to install FAF on linux, yet when I try to open a game it gives me this error and his error.

I've been troubleshooting this for a while, and the only conclusion that I can come to is that it cannot find the game. I've changed the game directory in FAF to "/home/dankf/.steam/steam/steamapps/common/Supreme Commander Forged Alliance" which is where the exe for the game is, but it still doesn't work. Perhaps I have to make something the launches it through wine? I'm not sure.

Thanks, and if you need any more info, lemme know.
