Premium Bundled Plugins – Activation Question

Hello,

One of the reasons we purchased Highend theme was because it stated there were 4 premium plugins that are free but I am not finding this to be the case.

I can not activate Visual Composer, Revolution Slider, Layer Slider and Essential Grid.
They work fine but I can’t activate them.

Layer Sliders gives the following error:
“It seems you’ve received LayerSlider by a theme. Please note that the auto-update feature only works if you’ve purchased the plugin directly from us. ”

Slider Revolution, Essential Grid and Visual Composer are giving the same errors.

Can someone please clarify if these premium plugins are full versions because that’s how it is being interpreted.
