Well I have had this game for about a year now and I have FO3 with 4 of the add on packs, The Pitt, Operation Anchorage, Broken Steel, and Point Lookout. I know there is another add on pack but I dont have that one, I think its the Zeta one. I am having a bad glitch at the end of FO3. After going into the chamber and enter the code I die or atleast it seams that way but then I wake up what looks like to be under a surgical table in Medical area in the Brother Hood of steel base. I cant move I cant do anything, I do hear the big mutant guy but that is all. I assume that having the expansions installed led me to the next add on but why do I glitch and stay stuck under a table? I have had two PC's that run this game great but up to this point in the game I cant go beyond this point. Please help me with this problem.

Thanks
