How to correctly disable shipping and have shopping cart function?

Hi –

I’m using MarketPress to let people purchase an online class. Under store setting > shipping I have chosen “No Shipping”.

When I start going through checkout I first have only e-mail under “shipping” (as expected) then Iget to stage three “Checkout” it’s blank, and then trying to go to the next stage “Continue Checkout” I get the following error:
