My game disc has no data on it.

[Urbanwanderlust]

I bought Black Plague from Best Buy yesterday and when I tried to install it I discovered that the disc was devoid of any data whatsoever. Earlier today I returned to Best Buy and exchanged the faulty disc for a new one and I ran into the same problem when I got home. I tried both discs on different machines and still nothing. What can you do to help me?
