I have a duel os system xp and 7hp. Medal of Honor Limited Edition is installed on xp. I was going to install it on the 7 side also but it went right to play single or multiplayer mode. I went with single player. Everything went fine for about 10min. then the sound distorted and the darn thing crashed. Is there anyway to keep this from happening or do I have to uninstall from xp and install on 7?
