Hello,
We have just updated the files. Please try to update the plugin in Appearance > Install plugin, if it fails to update, navigate to Dashboard > Plugins, deactivate and delete the current version, install and activate the fresh one.
You can take the recent version of the plugin in the forum profile.
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
