I was playing my copy of "The Walking Dead" Game of the Year edition for Xbox 360, and while playing Episode 3, I arrived at the part where you talk to Chuck on the front of the train and then have to go back and talk to Ben. When I did, my left stick movement was fine but the right stick icon was gone, so I couldn't initiate conversation with him and this couldn't proceed. I tried restarting the game, and when I opened my save again, all my save data was lost. My stats were still there, but it was putting me back at Episode 1. Is there any way to rectify this immense issue and get my save data back? I don't want to have to go back and play everything again to get back to the same point.
