Order Status Not Working After Marketpress update

I just updated to Marketpress I LOVEEE the changes...I was going to switch to a different Ecommerce plugin, but Marketpress was smart enough to add awesome features like Packing Slips, Invoices, etc.

I'm having 1 issue after the update: my customers can't look up their order statuses anymore. When they enter their order number, it says basically that the number was not found.

Assistance greatly appreciated.

Thank you
