Help with Payflow Pro Problems

Hi!

I am integrating Paypal Payflow Pro and everything is going well except when I checkout it says:
User authentication failed

I looked at your forum post
https://premium.wpmudev.org/forums/topic/marketpress-payflow-pro-not-sending-info-to-paypal

And
https://premium.wpmudev.org/forums/topic/paypal-pro-user-authentication-failed-on-credit-card-confirm-payment?replies=2

And it doesn't look like what I am experiencing. I have double checked that my Vendor/Pwd/User are all correct and even called paypal to see whats happening and they were unable to assist me. The SSL is working correctly. Can you help me figure out whats going on?
