This has happened to me and my boyfriend as well. We downloaded Episode 4, and went to play the game. I chose his save, and for some reason it was starting from the beginning. So we lost his save. It is back at episode 1 now

All 3 of his game saves were filled though, so the other guy's suggestion doesn't work for everyone.
I just tried to play my save, and it won't let me select it. I noticed it was trying to start at 1, so I didn't do anything since I don't want to undo my progress. So I am not sure what to do. I tried copying my game, but it will only let us copy from save 2 (which is at episode one.) My save slot 1 is on Episode 3.
Idk what to do. I don't want to keep having to start all over. We are now too far into the game and it just takes SO long.
