Activating my current Shopsite Pro Checkout and Hyperlinking it To My Current Website

Hi there, ? I signed up with [[login to view URL]][1] hosting and? also created a simple website. And was also told I could sell eBooks online using their WebSite Creator E-Commerce by CM4all. After signing on they said it does not have the capability for customers to download eBooks straightaway once customers pay for it. So they referred me to purchase shopsite pro - a 3rd party? store that can be hyperlinked to my website. ? I have bought it though and am unable to create this store online. No one can actually help me either in fatcow or shospite itself. I really need someone experienced to? run me through how i can add? my? ebooks to it and teach me how to keep adding as many books as I can. I need the shopsite store to? also be? hyperlinked to my website [[login to view URL]][2]? ? as well. I actually created that website using fatcow What I want to do is allow my customers who go to my website [[login to view URL]][2] , when they choose to buy the ebooks to download, they get linked to the shopsite store so they can pay for it then get sent a link to download the books, then for them to get sent back to my website again. Please contact me if you are experience at using shopsite pro. Thanks, Aysha
