Paypal has provided all of the information necessary to update. We have contact phone numbers, emails, and address all published on our web site and readily available. We're in the local yellow pages and have a picture of our office on the about us page. I think you can find my mug with a personal bio on there as well if you looked.
You can search your code for Server.CreateObject( it is in the include file associated with your payment named after PFPro. You would update the Server.CreateObject reference with the code provided by Paypal in their documentation on how to update this problem. Unfortunately we have moved away from the ASP and PHP server models and cannot continue to make code updates on those platforms in perpetuity.
I'm happy to talk you through it, but you are going to have to update the code and understand what you are doing to get it done. That means reading what paypal says you have to update and doing it in the associated spot in the code.
