I cannot patch this game. I have English DVD version (cz manual) 1.0.15.79. And patch (400+MB) states that i have not english version of the game. Autoupdater states, that game is up to date... :-/
i have the same problem as above
Try to reinstall and download the 400mb patch manually. This will most probably happen if your using a cracked exe to fix stuttering or something.
