I uninstalled and reinstalled. Purchased a new (used) disc at gamestop. Uninstall and reinstall. Deleted my local memory. No luck. When I play Halo>go to Halo 4> Select Resume. It loads about 70% of the bar and then stops. Music begins to flutter. I get tossed all the way out to the initial load screen for the XB1 Halo disk.
