My old DUATS account seems to be borked also.

It will not take my password, which I have written down in my wallet
so I would not forget it, and when I try to sign up again, it says it
already has an account for my certificate number and will not allow me
to proceed. Calling the 800 number for support was either perpetually
busy, or would ring forever with no answer. As a result, I have simply
given up on DUATS.
