I am having a problem with the Broken Steel add-on. I keep completing the game, go through the entire ending movie, get the clock (loading) screen, only to have my screen go black and NOTHING happens. I've tried several times and many different endings, and I don't know what else to try. I have unistalled and reinstalled the DLC several different times, and from several different points - ie before I leave the citatdel, at the memorial, etc and I still just get a black screen. It never opens up the two weeks later part. I know the content dowloaded, because I have had access to the weapons, creatures, etc. Does anyone have any suggestions?
