Thanks for using Slider Revolution. As you have received our plugin via a theme purchase, there are two options:
For setup and integration issues, please contact the theme author directly. If you want to update the plugin, you will have to wait for the theme author to include the latest version in their theme. With the latest plugin .zip file you can then do a manual update.
If you need direct support from us as well as automatic updates in the backend, you can purchase a plugin license from us here https://codecanyon.net/item/slider-revolution-responsive-wordpress-plugin/2751380 . The license key you receive will allow you to activate the plugin backend and will unlock the automatic update feature for you. When commenting on the Envato item page or submitting a ticket to our support system https://themepunch.support . Also, as a premium member, you’ll receive the benefits listed here https://revolution.themepunch.com/direct-customer-benefits/
