Account update problems

ADE seems to be stuck with my old email after I changed it in Adobe ID. This causes ADE to not sync my books, and I'm unable to remove the Adobe ID account for ADE - It only returns wrong password, and it's not the password thats the problem, it's ADE not uppdating the emailaddress.

How do I fix this. I want my books to be downloadable to the mobile app, and now its not working at all.
