I was reading on gamefaqs and a lot of people supposedly found a fix, I tried it and it worked for me. I'm not sure if I'm allowed to link it but it's not necessary anyway, you just have to log out of the PSN. I tried it and it worked fine, loaded up my ps3, logged out of PSN and then started the game and it loaded fine. Hope that helps someone!
Mine stopped today. Just got 16 hours into the game, 24% complete, saved last night, went to sleep, got up today and it hangs on Loading. Tried to start a new game and it hangs on Starting A New Game... :( I have a 60gb I got in October.
looks awesome, can't wait to try it
