I just got the Xbox 360 version from Amazon yesterday & played the whole thing on easy, everything went fine.  Today I'm going through on hard and its frozen 4 times, each time when it was saving.  Does anyone else have problems with this game locking up?  It might just be my 360 too, I'm still rockin' a launch system that's been sent to Microsoft twice already.

I played it on 360 a week ago and every time I used a force power it froze for about a second then continued on like normal, it got to point of being unplayable. Is every copy of it like this or did I get a bad one also?
