With the first CD, try holding down the shift key when you stick it in your optical drive; that will tell Windows to skip the autorun function. Then browse to the optical drive in Windows Explorer and see if you can copy the BeyondDivinity.exe file to a folder on your hard drive. If that fails, there may be something wrong with the CD itself. Problems during the install could be a conflict with an anti-virus program, etc but a simple file copy should avoid that.
It is possible, though not likely, that your optical drive is failing, and this is simply the first CD it has had trouble reading. Some drives just have trouble reading some CDs.
If possible, try a different optical drive. If you have access to another computer you could see if BD will install on it. Did you buy the game at a computer store or a game store? If the file copy fails, a computer store (or a game store with any display systems) should be willing to check the CD. Most places shouldn't give you too hard a time about exchanging the game, though I would try to determine if the problem is with your drive of the CD first.
