Company Of Heroes problem.

So, I downloaded company of heroes (Loading's release), mounted and installed it. Everything seemed to be in order, I played the first tutorial mission before i had to do something else and exited the game. When I was gonna play it again the game crashed during the loading screen of the mission, and I get promted to write what i did before the crash and send it in. (Not normal error report like you always get in windows). I've tried uninstalling and installing again, updating etc, but it's always the same: works first time i start it, second time it crashes. Anybody else experienced this that can give some hints to what can be done to solve it?
