Yeah, account panel was changed to only accept the email as username a while back.
I'll reset your cPanel password manually, it is strongly recommended that you do a password update once I done so, if you chose not to do that, you will NOT be able to use the login to cPanel button in the account panel (you'd be taken to login page but the automated attempt will return a "login fail" error).
I've sent you an email to the address on file with the new, temporary, cPanel password.
