same problem here. the first time the dreaded black screen manifested, i was over 17 hours in and on my second planet, (it happened to be nar shaada) after i beat the twin suns with atton (the two twilek female assasins) and the game goes back to the ebon hawk. the dialog between the other companion finishes, the load screen pops up, finishes and then...............
nothing. so i started over from the begining. NOW i get to the point where you switch control over to T3 the first time and........
nothing the load screen finishes and its done. i am using the game disk as my xbox is of the UNmodded variety. and i cant get this sucker to go past that point. I have restarted four or five times always the same thing. I even went and bought another copy of the game thinking it was a bad disk.....NOPE, same stuff, I went and exchanged the disk at blockbuster for a different one (got a friend who works there) same thing. I have emailed Lucas a couple of times but nobody there seems to be able to help me. so now i am into this game for over a hundred bucks, and i can only play for about twenty minutes before it locks and i am screwed. I have a newer xbox (halo edition) and it has a philips drive so I am hesitent to believe that its my console. if anybody has any advice i would be most apreciative.
