I just went through the same thing tonight. I managed to get through by clicking on the lost password link. After it sent me a new password I clicked on the set new password link. I then had to log in with the password sent in my email. After that on the set new password page I had to enter the password sent in the email again and then the new password twice to reset the password. Seemed overly complicated but it worked. FYI.
I believe there may have been a change to the minimum number of password characters as my old one was less than 10 and now the minimum is 10 characters.
