Continued problems with PayPal Pro integration

I am trying to integrate Paypal Pro into the form. I entered and verified the credentials and it works on the credit card side but not Paypal. Why I try the Paypal option I get the message: 

Please wait while we are processing your request...

and it goes on forever...

I just tried your form, and it transfer me to the PayPal page without an issue:

Please try again, this time open your form in your browser:

Let us know if you need more help.
