Bugged on Dxun

My second visit to Dxun I ran into a bug. When I get to the camp it may black out on loading entering camp any of the 3 ways. When I get into the camp if I have 2 companion slots filled then they are gone. However all or most of my crew are in Malicors(sp) den. When I speak to the guard who takes me to the suttle then it begins to load and blacks out or gets stuck on load. I tried verious variation and it does not change this. Spent many hours and deleted many saves and files to open up Xbox and no luck. My jedi was gray (neutral alignment) and I had pretty much done all of the side missions of the available other planets at that point besides doing the cave on D---(sp). Also I had not upgraded my Jedi and pretty much unable too at this point...since I errased all of my saves thinking that this must be part of the problem, I had to start again from the beginning... very frustrating!!! Still a great game, but save often in many areas just in case this or something similar happen to you!!!
