American Express QBDT Error 591

I've been trying to setup the American Expresss QBDT bank feed and when I enter the login for American Express it keeps returning to the login page.  When I cancel I get an Error 591.  I've double checked the login is correct and I've check Amex to confirm QB is not already linked. It's happening for multiple client's books.  Is this a common problem people have been having?
