Is there such a thing as a bad disk? I bought Fever 2003 and it will not load. I get the dirty disk/won't recognize disk error when I put it in my xbox. All my other games work and I just recently got xbox to replace the cd drive and since then, I haven't gotten any errors on any of my games. Fever has no scratches (a few now since I tried cleaning it) and I even did the 45 second boiling trick, but that didn't work either. I guess I can return it for another one, but is that necessary? Can it just be a bad disk?
