I finished episode 2. As episode 3 was starting, I paused and went back to redo the raptor attack ending to to episode 2 again to get the achievement. I got it, then went to continue my game... when I click load on the main menu, however, I briefly get the Loading screen and then it goes black and the game never comes up. My Xbox isn't frozen, as the guide button still works and I can view who's on Live or whatever else. The game just never loads.
I thought to myself, well, no problem, I'll just go to Episode 3 on the main screen and click start episode. However for some reason when I do that I get a message asking if I'm sure I want to restart over again on Episode 1.
So... basically I'd love some sort of idea of what I can do to continue my game without having to play through the first two episodes again.
