Broken Steel Glitch: Fallout 3?

Hey, I just finished playing the campaign to Fallout 3, and I had installed broken Steel. So, when I killed all the people in the Purifier room, we talked to the person on the Intercom, and I risked myself to activate Project Purity. I know many people have glitches, people not speaking over the intercom, but mine is different. I watch that little movie and everything, and then it says 2 Weeks Later. I am lying either face up or face down, and I can hear A Mr.Gutsy speaking in the background, and no one is talking. Let me be specific here, I don't even get up, all I can do is sit there looking at the ground our ceiling, I am not sure, and I can not see much, but I sat there for so long, and I tried to undownload it and everything. I even made sure that the "Broken Steel" sign came up before I entered the Purifier room, and it did. I am not sure what Is wrong but I need as much help as possible. Thank you in advance. (and if more information like specifics is needed, just type it down and I will answer the best of my ability). Thanks again
