IT WORKS NOW!!!!!! I bought a scratch repair kit from Wal-Mart and used it, but it didn't fix it. So the next day (which would be yesterday) I went to my neighbor's house and used their CD burner to copy my game. The copied disc works. I'm so happy! Well thanks anyway guys.

P.S. Someone can close this thread if they want. I prolly won't be needing it anymore.
