Isonic

I tried to play this game but everytime I get going good the screen shatters and I can't see anything. Can someone please help me?

When I load the game, I get to do every option normal. But when I start playing the actual secnario, the game view will go shattered like the moniter has blown up. It is all distorted. I have to hit ALT F4 to exit and reboot to encounter the same problem everytime. HELP!!!
