Your store is running Shopsite Pro 10 r7.2 which is a patched version of the original 10.0 release. Since that release there have been 4 major releases, 10 sp1, 10 sp2, 11, 11sp1 and just recently 11sp2 (linux only so far). So the version you have is about 3 to 4 years old. The videos on the website are probably all using newer versions of ShopSite. So some parts of the videos may not apply to your store.
Talk to your host about getting updated to the latest version so you can benefit from all the features added since version 10. You can find a list of the new features at.
