MarketPress Checkout BOTH Paypal Gateways

OK guys, was looking to launch tonight, but can't until this is resolved.

I am looking to finish testing, making some product UX pathway changes (how to end up buying a given product), and then moving from http://mydomain.com/wordpress/ to http://mydomain.com/

Here are my challenges currently:
1) When checking out with PFP (credit card), it never came back to the confirmation page. It completed the checkout, charged the card, and then went to a blank page:

https://hamptonbayremotecontrols.com/wordpress/store/shopping-cart/confirm-checkout/

2) Then I did it with PEC (Express checkout), and it did the same thing.

HELP.
