Can Someone help me Get my Forza Motorsport 3 content disk to work?

I recently bought Forza Motorsport 3, and it came with a content disk. That disk allows you to download all the DLC for the game. When I choose "Install Disk 2" it says, disk cannot be read, however, the disk is in perfect condition.Can Someone help me Get my Forza Motorsport 3 content disk to work?
I love forza 3 - too bad mines is destroyed too...

Anyways!

Is there a crack in the middle of the disk? If so it will be caused by that.

Take it to blockbuster or something to get the game 'cleaned' (takes scratches off if any)

clear the system cache - theres sometimes data inside that, that stops it from installing.
