MotherShip Zeta Help!

[DoppelgÄnger]

Well, I just got the Game of the Year Edition of Fallout 3.(Which is friggin' great.) The first place I went to was Mothership Zeta. I pounded most of the way through it, BUT, after I got back in from outside the ship with the space suit, I accidentally took the teleporter to the lower deck right when the girl said "Whoops, sorry. Let me get the door." So I go back through the teleporter, the door is still locked, and the girl won't move. I have talked to everyone in the room.(Even tried to kill the girl. >>) Yet, nothing happens. It is the room where there is a glass window on the floor where you can see the Earth.(Xbox 360 Version.) If anyone can help me, I would be very greatful. I don't want to start my game over!

Is there an auto save from before you went through the teleporter?
