Allied Assault problem?

[Setz]

Trying to play Medal of Honor: Allied Assault and when I open the game the screen turns gray and I have to use Task Manager to end the process. I have no idea what the problem is.

2.8ghz 2600+, 1024mb 400mhz DDR RAM, 9800XT. I pass the requirements with flying colors, and I have the latest drivers for everything. The game is pretty old though.

I'm also finding minimal help from Google and virtually no help from EA's website.

Nevermind. I think I found the problem. According to Add/Remove Programs, the game is only 3~mb, meaning that only 3mb installed which most likely means my discs are corrupt.

Gonna try downloading an iso and using my legit CD key. :|
