I'm trying to register for nabx but I keep getting this message... "ERROR: You have attempted to access this form from an unauthorized referer. Access denied!"

If anyone else has problems using the registration form, please let us know asap. Provide as much information as possible about what you were doing when you received the error message.

Tips: Do NOT use your browser's 'bacS-P-A-M-L-I-N-K- button while processing the form and do NOT close the browser window until a payment method has been selected and you've received the welcome page of our site.
