Protected Content Payment Gateway Status

I'm building a Protected Content site with MarketPlace.

I have set up Protected Content but can't seem to get any of the Payment Gateways to be be used. I can register a user but no payment links display. I tried both Pay Pal options (is one better than the other?). The data seems to save fine, and I've set up the IPN, but all of the gateway status say (unknown).
