I can't apply the multiplayer update that came with my purchase. I just installed the game in Bottles, a game manager for Linux, and everything works except that I can't join any servers. I get an error message that says "invalid host". Is there a way to manually point the executable to my game directory? I tried running it from inside the game's directory, didn't work.

Edit: Sorry, this is for Shadow of Chernobyl. Forgot to add that in the subject
