For getting on with the Thieves Guild quest line, i ran into some trouble. Upon entering Markarth, the whole system freezes. Not just the game, but when the loading screen pops up, it loads about 3 to 4 seconds and then it freezes up. The music stops and the screen freezes. Im not even able to quit the game og shut the ps3 off from the joystick. the only thing i can to is hit the on/off button the the system itself. this is a major issue, at least for me, but i cant find any others, that have encountered the same problem. Im in level 33, but even when i was still level 5 and had a small amount of saving data, this issue was still there. Any advice or fixes?

Thanks!

It happens sometimes in certain areas at certain times...I believe it is called a dead cell...create a new manual save and delete all other saves,then before entering the area that crashes,wait 73 hours in game time,then try entering,if that don't work wait 31 days in game time...it fixed it for me before when entering the Riften Apothecary kept crashing,also another time it kept crashing when approaching a farm near Whiterun...
