No idea really, maybe you didn't uninstall it correctly. The Movies sucks anyways, be glad its not working.
To fix it you might need to edit your computer's registry. I'm not really sure how. Run edit reg or something.
It doesn't suck, it's a brilliant game, very fun and original. Anyway, not sure if i have the same problem as you but i'm unable to install/play it since i installed Windows Vista home premium a couple days back.... :(
