Shipping charges are not included on orders and invoices

I gone over your procedures over and over again and the same thing happens. In the general section for MarketPress eCommerce the system ask many question about downloadable products and it seems the system identify all products as downloadale items. Therefore, the system does not include shipping charges to orders. I had this problem with MarketPress Lite and I was informed if I switch to MarketPress Ecommerce premium the proble would be solved. I have switch and I am still having the same problem.

MarketPress Ecommerce premium still is not generating the shipping charges on orders. I need help. This is causing money. I am unable to do business. Thanks.
