Hopefully this will blow over in an hour or two, but PayPal is currently having some internal issues or is undergoing maintenance. This is causing a delay in the system that contacts our server with your new payment information, so please be patient until they fix the issue. You will also notice on their site that it may take a few tries to log in, and may give an error message telling you to retry. I can only assume this is part of the same problem.
I apologize for the delays, these are unfortunately beyond my control. If they dont get fixed very soon I will see what I can do to ease things along here.
Update: The problem seems to have cleared up and payments are being processed correctly once again
