LayerSlider license issue

Hi

I just recently purchased and installed the Highend WP theme.

I am having a issue with the LayerSlider plugin. At the plugins page I see the following error message under the plugin:
“You need to authorize this site in order to get upgrades or support for this plugin. Purchase a license or enter an existing purchase code.”

I just installed the theme from the zip file. I can’t find a license code or anything for this Layerslider in the email’s I got when I purchased the plugin.

Could someone please let me know what the steps are to resolve this error.

Thanks,

Andrew
