Okay, so I'm in Vera's room and want to get into the elevator. I stand in front of the microphone and play her audition tape, but it still won't let me in even though I played her voice. Can someone tell me what's wrong?

Have you merged the tapes at the reception desk? I had one tape in my pip boy when I first went to the elevator door, but it wasn't the one I needed. So I went to the reception desk, in the lobby I think, and merged the tapes. Then I spoke to Christine, and she spoke the words into the intercom. Hope this helps.
