Need Help NOW - Pro Sites auto payment blocks out users

My first Pro Site owner just had her second payment automatically deducted through PayPal. This coincided with a number of issues:

(1) Her blog background disappeared
(2) Her header image disappeared
(3) She can't get into her dashboard.

When she goes to it takes her here instead:

This is the PAYMENT page. But she has an automatic payment that WAS made yesterday through PayPal.

Please help me resolve this. It is not only embarrassing, but potentially very damaging to my clientele.
