Sorry, BBW! "Cyclic redundancy check" always has to do with corrupt discs. But there's something that can help you, it has worked for me a couple of times: create an image of the disc (you know, *.iso) on your hard disk, then burn it to a blank CD-R and it should work. The whole thing is to get the image ripped - can't be done if the disc is too damaged or if it has some sort of fancy protection.
