Here is the place to get and give support to your fellow gamers. This is NOT an official game support conference but a place for general tech support. All questions are welcomed, basic, advanced, software or hardware.
As no one has answered this yet, have you tried the Cross of Iron subforum?
I don't have te game but personally I'd say it's a compatibility problem between the ageing game and a new OS and new drivers. I don't know how up to date the game still is, but if I were you I'd go to your graphics adapter menu and tick off some of the "newer" options... like AA and FSAA and what not. Cross of Iron may not recognize them and cause the error... just a hunch ofcourse.
