Buying a theme which is bundled with Visual Composer and Revolution Slider ( like our theme) does not mean that you also buying a license code of that plugins. So you just don't have a license key and can't get automatic updates.
You can purchase separate plugins on :
We bought an extended license to be able include it in our theme, and we own only one license key (as well as in case with single license), theme buyers are not allowed to use that key.
If you want update it you need wait our theme update new version , or you can buy Regular License for you
Thank you for reading.
