I'm struggling with the same issue. In the summer of '11, I bought the '5 episode pass' when it was on sale. The fifth episode wasn't out at the time I think, but I downloaded the other 4. Now I want to play the entire game and look for episode 5, and it's nowhere to be found. Not only that, but when I browse through my history on the ps3 itself, the 100kb pass file has changed into 'episode 1 free' or something. It doesn't even recognize I bought every episode at some point. On my transaction history on the SEN site however, it does:
Here (and on ps3 itself) it changed to 'episode 1':
So, 2 problems actually: apparently I don't have a 5 episode pass anymore, and 2: it's not even on the store anymore apparently (EU PSN).
I've played ep1 and enjoyed it, I'd really like to be able to finish the game
