Does not work on worpress 4.9.8 at all

I installed this plugin to make use of the one free template, since all I needed was a very simple landing page, however, it does not work, you select the template and it does nothing, you can’t edit any content or anything, every option is only a button to upgrade to the paid version, but they can even get one template to work, so I am not paying for the full version. The worst experience with a free plugin I have ever on WordPress.
