All plugins are external extensions which are included into theme because for each product we purchase “Extended license” and that’s why we are able to include it into them. This plugin works fine without activation and you can always get actual version if you want directly from us. The plugins can be downloaded from this link http://www.8theme.com/download-plugins/ . We update plugins with theme updates from time to time so plugins will be also updated with each next theme update. The option with registering of the plugins has been already added to plugin and this only allows you to get automatic updates and support for this plugin directly from an author if you need. You don’t need to register this product because it is not required but if you want to get those features, then you need to purchase this plugin directly from the author. This is how it works for all themes on Themeforest and not only in our case.
