My Demigod disk won't read.

I bought a hard copy of the game, took it home, threw it in the drive, and it sat there for a few minutes making noises, then told me the disk was blank. I tired my friend's copy of Demigod; same thing.

I'm currently trying to update my drivers, which is proving difficult, as they are all in bin files that won't open like they usually do.

I did pay for the game ( I got a cd key and receipt and all knds of stuff) but I can't play it. Infuriating.

Any insights?
