Google Checkout & Digital Downloads in Marketpress not setup correctly

I’m having an issue with Marketpress. If somebody purchases a digital good with Google Checkout from a Marketpress store, I have to login to my Google Checkout seller admin, find the order, and click ship in order for the download link to be available to the customer. I have all the proper URL notification setup, chose the serial # option in the Google Checkout Integration options. Can you guys please look into this when you get a chance?
