Samuel,
To download, you simply need to get the files from the
"My Subscriptions"
area. You can also access that area from the link in the login area in the top right.
Once you download it, you install it like other Joomla extensions. To configure, there are a few steps, but our configuration guide, below, should take you through each stage:

If you run into any issues, just let us know, and we'll help out however we can.
Good luck,
Alex
