Hello,

I am sorry that you are experiencing issues.  

A PayFlow error code of 12 usually means that the credit card you have on file with Paypal has expired possible.

Below is from Paypal site:

Check the credit card number, expiration date, and transaction information to make sure they were entered correctly. If this does not resolve the problem, have the customer call their card issuing bank to resolve.

Let me know if there is anything I can do.
