Just finished the last mainquest of the thieves guild (putting the skeleton key back) and now I decided to do these radiant quest.

But if I want to talk to Delvin, Vex or Tonila they just say "I′m busy , talk to Brynjolf".

Also the Bartender refers to me as the new one even if I am a nightingale.



When I collected money for Brynjolf and he wanted to "show me around". I saved and quited the game, when I loaded the file he walked into the Cistern but when I entered the were all like "Get out - you don′t belong here" so I got lost, done some other quest (mainquest for example).

When I got back I "fixed" the bug by entering



to start the "loud and clear" quest (the one with Maven)

and

to make me a member of the guild



How can I fix this? Could you guys please help me?
