How do I deal with this? darn people put registration and login on the same page an kee is only filling in the registration part (which I have already done).

Have you tried pasting the email and password into the login form and then saving an updated copy of the KeePass entry after you click the login button? That’s usually enough to solve this sort of problem (which is typically caused by saving a new entry after filling in the singup form rather than the login form, although that’s not the only possible cause).
