I think I know his problem and you won't like to hear it. Cyclic Redundancy error means that it had trouble transfering a file from your CD. Download
this program. It will check your CD and find all errors. If it does find errors that means you have either a dirty or scratched CD. Get some CD cleaner and wipe it off, and if there still is a problem you have a bad CD and need to exchange it (if your still under warranty). Go to this site here ->
