I've un- and reinstalled the game repeatedly, I've updated the NET framework to version 4, but every time I hit the play button, I get a wallpaper image, and the computer pretty much freezes up. I can get the mouse pointer to move, but it disappears around the game logo, and I can't alt-tab out or get cntrl-alt-dlt to shut down the game. I'm pretty much forced to reboot the game at this point. Any idea of what might be wrong?
