I have two accounts for Skyrim and I keep the saves for each on separate USB drives. One of my accounts is level 74 and I have never had ANY problems with loading. The other account is only level 9 and out of nowhere i am unable to load it anymore. The
xbox doesnt freeze, it just doesnt load. I checked to see if it is corupted and its not. I tried reducing the saves to only three, clearing the system and game caches, starting a new game and then loading the old saves, etc. I even moved the saves that
wouldnt load to the same USB as my level 74 account that never has any problems, and it still wont load. I dont get how my level 74 account has no problems but my level 9 will no longer load. I left my xbox on for 2 hours and it was still loading!!
