Query: CD's dont even play

I bought this a little while back and did the 5 day inferno and the cds worked okay because you just use 2 for this part of the workout. I used my xbox and even the 45 one skipped a few times but nothing to bad. Afterwords I ended up moving and the xbox got misplaced. Non of the Cds work on any of my dvd player or even my computer and I just bought a brand new Blue-ray player with everything on it. Afterwords I got the xbox back and still there are only a few cds that play. This is ridiculous and I think they should not even be making products like this and selling it for so much money. I am very very unhappy and dissapointed! DO NOT BUY!
