Hello,

I have logged in to your site and checked there are no updates available currently for slider revolution plugin in the website. You are already using the latest version of plugin.

WPBakery Page Builder and Revolution slider come bundled with our theme but they can’t be activated with our purchase code. Actually, you don’t need to do this. Only in case you want to get free premium support from its author, you can purchase it from Codecanyon. But it is not necessary since we will always provide you with the latest updates.

Best Regards.
