Spore Problem

Ok, so I love playing spore, but in the space stage ONLY i have problems. So times the game will glitch and this wierd ghosting effect will happen like black lines going up the screen, but yo can still see stuff, sometimes the game recovers sometimes it will not. I know its not my computer because its on xps 630i and 3 months old and dell just fixed it a while back, because it was broken from the start. So i know its not the video card because all the other games i have work like a charm. And my spore disk is a little scratched. So is it just the spore disk itself.

Thanks
