vb.org Archive - View Single Post - Paypal Donations (With Instant Payment Notification) -- RC1 (Public Testing)

I got an error message saying:

"Error Detected

This invoice has already been paid. For more information, please contact the merchant. "

I don't understand, I am trying to test the paypal using a visitor account. I don't even get to enter my credit card information yet. Just click on the donate button and I got the above error message? Why?

It was working twice last week before I installed the Archive hack. I wonder if the archive hack screwed something up???
