I was experiencing what many folks have wityh the PS3 version of the game: After Episode 1 ends, and the preview for Episode 2 plays, the game freezes and did not show the stats or credits. There looks to be an X to click, but it can't be done.
FYI: I have a PS3 Slim, and purchased the Season Pass.
Here is what worked for me to fix (no thanks to tech support here, btw!)
I reinstalled the game and unlock key from PSN, but kept the game file. Once it reinstalled, I continued from the last save (at the motel, Glenn leaves, talking with the other group members). This time, the game finished (lights out), preview played, and I saw my stats and the credits.
OK Telltale! Ready for Episode 2! Any month now! :p
