MarketPress Not Working with 2checkout

I am unable to get the product once ordered to show up on the site as ordered. I did a test in 2checkouts for 1.00. I set the return url and set the direct return to header redirect.

Not sure what to do. Please help.

This is the code that was sent back to the website, but nothing appeared in the Manage Orders Section. However 2checkout has the order.
