As a sidenote, our mini-framework powering all our Joomla templates will be updated within the coming weeks to a new version, supporting Joomla 3.x exclusively.
Using the new Quickstart Packages
You will need an active subscription for the template(s) you're interested to use obviously. Grab the zip file and upload it to your server. Extract it and vist the folder you extracted it in from your browser. The setup/restoration process will start. Fill in the required details and you should be ready to use the demo site for your chosen template in a few minutes time.
