I was in the middle of the Torturer's Tomb and all the sudden I got an error message and had to exit out of the game. When I restarted the game it told me my game data had been corrupted. When I got done with the torturer's tomb I had two tombs left to go through and finish the challenges and I would have been 100% done with the game. Is there anything that I can do to get my save back I really don't want to have to start everything over again and unlock all the stuff I had unlocked again.
