Hi Guys,I have been trying to purchase the B744F. I add the product to the shopping cart and then click on checkout, but the screen then comes up saying, your cart is empty, please add something to your cart. It's getting kind of frustrating as it happens with all the other products too.Any help appreciatedJohnathon Neilsen

Sounds like a browser security settings issue. Make sure PMDG is a trusted site.

Try logging out, adding the product to your cart, then logging back in. I seem to recall someone had a similar issue recently and this fixed the problem.
