We are having reports of errors with registration forms being processed, and problems with payments. We are sincerely sorry for any trouble that you might be having. We are working tirelessly to try to remedy the issue.
Primarily the issue seems to be with processing payments via credit card and the integration with the form connecting with PayPal. However, it seems that people are having some success completing their registration using PayPal Transfer as their payment method. If you have PayPal, please try that method.
We will make an updated post when we have fixed the form.
