I was trying to join the theives guild and I had to steal a ring but then Brynjolf gave me another task to do. I did that and then he gave me the quest Taking Care of Buisness and he keeps telling me to goto the underground place but he won't leave the Stand area where he was attracting the attention. Everyone is still around him but he isn't saying anything to them. And when I talk all he says is meet me back at that underground place. I tried stealing the ring and planting it like the original quest told me to do but still nothing. Any way to fix this?

There's already a thread for this:
