Password not working

After someone creates their account here:
http://www.lakesawyersouth.com/arb-registration/

and completes that, and goes to create the ticket here:
http://www.lakesawyersouth.com/arb-application/

The password they JUST created, doesn’t work. I’ve even tried, as Admin, under users, to create a NEW password, save it, and that one doesn’t work either.

Any help will be appreciated.
