Looks to be a great app, but cant upgrade to premium...

I want to use this app to its full potential, but every time I try to upgrade to premium, I get the following error message: "This item is currently being modified. Please try again later." Ive tried to purchase the upgrade multiple times over the past 48 hours and I still get the same message...
