Store theme settings

Hi I have installed the theme, but am not able to access the 'classic' and 'modern' on the dropdown in the general settings, store theme. There is a hyperlink that says to upgrade, but once I select that it takes me to the home site...with then the same download I have already done.

Is there a service I need to upgrade to select this? What I am trying to get is the set-up of products that is shown in the demo.

Hope this makes sense:slight_smile:

Thanks in advance!
