Anybody experiencing trouble with lockups? I was playing Resistance online and suddenly the game froze - not just my controller as sometimes happens but the whole game. Holding the PS button made the sounds like the menu was coming up but it didn't come on screen. I have logged a lot of hours with Resistance online and this is the first time I've run into this problem, an hour after downloading 1.5. Anybody else have a similar experience, with or without the update?
