Didn't read through every post so sorry if someonesaid this already but last night mine froze 3 times in a row so i went online to see if anyone else was having a problem and saw that someone said to try and turn off auto sign in to the Playstation Network as it's a problem with the game trying to connect to the servers while loading or something. I tried it and it worked I had no problems at all after that so it's def worth a try. Good Luck!
Edit: ^ shoulda read that post first haha Glad ya got it working.
