So I wish I could be more descriptive in what I am going to say, but I will try my best, and hopefully somebody can help... I had firmware on my xbox 360 added in September 06, and have been using it and playing my backup games since then. Recently I got the "Red ring of death" and my xbox stopped working. So I removed the firmware, sent it back to microsoft and now have a new xbox. I took it in too get new firmware and he added it (I believe it was ixtreme?), and now I can't play any of the backups I have played all along (it says Unreadable disc), with the exception of Tiger Woods. I have downloaded a few new games like The Darkness and such, but they do not work either... Can somebody please tell me what is wrong. Thanks in advance.
