Okay So I have a BenQ flashed to LT 2.0 and everything was fine. I made a backup copy of Halo Combat Anniversary, and when I tried to go on live it said Xbox disk could not be read. Now it is doing it for modern warfare 3, Halo, and Skyrim, the pictures of the game come up in the dashboard but they won't launch. Nhl 12 works, i was thinking it may have something to do with the new format on disks, because the xbox says it support the disk. Note: Modern Warfare 3 worked before i put in halo.
