Can't view order statuses on the front end

Hi, I noticed that on previous versions of Marketpress that you can put in an order # on ~/order-status and find details on that order, but now all I get is "Oops! We couldn't locate any orders matching that order number. Please verify the order number and try again."

I've changed the subscriber user capabilities via the Store settings but I still can't view orders of any kind. Please help
