I'm confused about your Paypal add-on. There is a note that says it doesn't work with the "new" Paypal Pro.

That link compares Paypal's current services. I have a Pro account. So, will your Paypal Pro add-on work with my forms? If not, how do I process payments? I simply want to collect credit card payments through a Gravity Forms order form.
