ps3 – Identifying Numbers and Identifiers on a PS3 Disc

You have to enter the game when you are logged in to the Playstation Network.

The game will ask you to update and this update will install the trophies.

But if you already played the game, you will have to play it again in order to unlock any trophy.

I found an answer (or maybe "work-around" better describes it). I tried the suggestion jwaddell made and was still encountering the freezes. Working off a suggestion I saw on the official Playstation forums, I disabled subtitles and game hints from the Options menu. I also had been running straight up the stairs and looking to the left (you see a murder of crows sitting on the floor if you look left).

So, with subtitles and game hints disabled, I ran halfway up the stairs, pulled out my AK-47 and strafed up facing right. Lo and behold, there was a shotgun MOB waiting for me. I dispatched him with a well-placed headshot and then moved out through the doorway. No freeze!

I am not sure whether the freezing was triggered by the subtitles, the game hints, or glitchy AI becoming over-excited at the prospect of shooting me in the back of the head unawares. In any event, I'm now past the customs house, have re-enabled game hints and subtitles and am mercifully freeze-free thus far.
