I am finding that also. there is no documentation the readme file just has a link in it. Would it not be more suitable to bother to write a how to, even a how to install when you have to upload manually as there is nothing tell us what permissions we are supposed to put and I gather we must have to set permissions as it is all broken for me. Half of what you say the premium theme has is missing for me, so either it is not really included or something is wrong with the upload. with bits and bobs everywhere with no real order. still trying to figure out what pages are created for product when I do not have a product tab and I created a page in every other section and still cannot get the product to see anything.
I simply do not understand it, mainly because half of it appears to be missing and broken on a fresh wordpress install also.
Sadly this implies that support is useless as I would not have even had to post this is you had bothered to include some documentation on how to use it, or even simpler how to install it when you have to manually.
Because of no documentation and a faq that has nothing of any use, I will not be buying another template from here and I was going to buy many of them if not all as I create many WP blogs. This is teh only template I have ever had so much trouble with.
Get your act together and spend an hour or two on your customers by writing a complete how to! will do you a world of good and may even get me back as a customer!
Spend some time on your customers please!
