Did you install the patch before playing? I just played this a couple of months ago for the first time. I installed the patch before I ever started a game and didn't have any freezing issues at all.
Yes I did it is required everytime you play it but that didn't work. Well I don't care I sent it back to Gamefly. waiting now for another game. Atari is sad they should've fixed that part on chapter 5-1!
Theres nothing special with Sony for help. <a href="http://us.playstation.com/playstation/psn/visit/pr
