Hi, I'm having trouble starting the game.. After i start it, I get an error saying "To run this application, the resolution of the screen should not be less than 800x600".. I have done all things nessesary to run in XP.. Changing compatibility and downloaded the latest patch (v1.2). I don't know what it is, if its my widescreen, my graph gforce 8600 GT or dualcore.. Please help me, i love this game to much
