ok, so i've only been playing online for a couple of days now and at first everything was ok. but now i can't seem to find a game. after selecting find a game, it stays on "downloading game settings" and doesn't load anything. it loads my stats and ranking but cant find a game. also, if i press circle to go back and select private match, it freezes the screen. music plays but i can't move or go back or anything. i end up having to reset the ps3. i know its not the disc because it was fine before and i havent messed with the firewall settings or anything. Can anyone give me any suggestions or past experiences. thanks in advance!
