I have a problem with entering to vault 101. I finished the game, but I can not do quest "trouble on the homefront" and I can not get the Medicine bobblehead because I can not enter. I'm trying to get the new password with radio and get access through the control pod but it's impossible. I tried as the guide says getting radio "Vault 101 PA system" and I get a signal lost message instead of the code. I tried to go my last saved game with level 6 but it does the same.
Anybody knows any way to do the quest and take the bobblehead??
bye!
