Why can't I log now, it says email address already taken, once I am in!

i have 2 twitter profile registered with same email address, and i can't log on now. First one was apparently removed, but that's not true. Twitter, as Facebook, never delete all information from a user, right? So now I can't change anything on my profile. And old profile still exist.
