The disc drive won't read the Crysis 2 disk.
It spins intermittently and then stops.
Every other disc works in this drive (including Crysis 1).
The Crysis 2 disc works in every other computer I've tried it on.

Running Vista 64 bit

Already tried making a .iso using another computer and bringing it to this one.
It installs, but won't accept my CD key

WHAT DO?

Edit: Fixed it by splitting up the .iso file into segments. Works fine now. Thanks for the help.
