[Major Malfunction]

I found my dvd disk and i installed the game but i get a black screen and freeze when i try to play it. Since steam is about 99.99% reliable (for me atleast) i tried to register the cd key with my account and it game me the invalid product code message. Is there a way to remedy that?
