My son bought Rockband for Ps2 today, and the disk is saying there is no data on it... We took it back to Walmart, exchanged it for another , and the same thing happened... Our Ps2 works fine on all our other games. I went online this evening, and noticed that a lot of others are having this same problem, and one common denominator is they got them from Walmart~! I was wondering if others are having this same problem. We are taking it back tomorrow, to get a refund... But my son is very disappointed. I am going to talk to the Manager, and suggest he check out the disks in their system.
