I've been trying to get my event set up with Recurring Payment for my PayPal Pro account. I added the APIs and when I try to register to an event, it goes up until you input the card info, then when you click on the submit button, it take you to a page that says "Sorry, but your payment was unable to be processed. Please go back and verify your information is correct."
Any one come across this problem? I have tried it on both the sandbox test APIs as-well as the Live APIs.
