Hi everybody, I recently got a chipped Xbox for Xmas and it came with a couple backups, everything works fine and the backups still play considering I jus updated the system so I could use the Netflix App. My question is, lastnight I made a backup of my Forza 4 disk and it will not play...it says "unreadable disk" is this due to me recently updating the system or needing a new mod update? I do not know what chip or version of firmware I have.... Excuse my ignorance on this subject
