Did anyone resolve this? I am getting the same message. Any help would be greatly appreciated. Thanks!

Sorry to annoy but I when the page is redirected back to checkout_payment.php It is attached with error_message=Credit+Card+Error%21+Please+try+again. Looking up error 21 in the payflow pro book it says this si a "proxy write failed." Any help on this would be greatly appreciated.

I am having the same problem. Although for what it is worth the software program I programmed to go through Payflow Pro has always worked except for today it does not. Payflow's test server seems to be busy today. So I am going to keep trying through the program that has always worked on the test server and when that comes up I will let you know. At least then we can't blame paypal. B) Please let me know if you find anything... like I said I am getting that exact same thing.
