Oh? have u tried to quit game and and start up ME3 again?

Try shutting down your PS3 too, i always have problem like you but whenever that happens I just reset PS3 and everything will be back to normal.

If still cannot, try again, exit game, sign out PSN, then sign in back and restart game.
Sometimes need to do more than once.

f still cannot then maybe EA's shitty server fault, just don't delete your precious game data 

Agree..try everything..just don't delete your game data..

i think it happens once to me..the store crashes and prompted you to restart right? i have to reset my ps3 twice...but after that, all is good..

Why not wait? or if you find some way of copying the game data

Oh mai..Tell me you have backed-up your saved data..otherwise, say goodbye to the saved game datas..

Happened to me before. I had always experienced freeze, maybe 8-9 times from day 1 till now. Luckily, everything ok after it run recovery mode.

How do you force shut down your ps3? If by pulling out the power cable, corrupted data is very likely to occur. Hold down the power button is much safer.
Sorry bro. Like I said before, they can't do anything. You must file a complaint within 1 week after the operation ended. After that time period, they can't issue any commendation pack. So make sure you file a complaint on Thursday or Friday after the operation ended, wait 3-4 days to confirm you does not receive your packs.

Every time a ps3 is force shutdown, a recovery mode will be run automatically after we turn on the ps3 back. (I'm not sure what its called, some kind of recovery process to check and fix corrupted data)

so, now it's ok already or still a problem?
