WP Plug-in license Key not accessible

I downloaded the Sliper plug-in through Envato elements. I licensed the plugin for a job, and received a license key. This key is for envato but not the activation key for the plug-in itself. I did not receive the activation plug-in and do not know where to access it. When I log onto the envato market my account is different then the envato elements account and displays no items in downloads. I do not want to have to repurchase the plug-in on the market since I have an elements subscription.

Elements items don’t come with these.

Any item that requests them is simply asking for the purpose of auto updates etc. which is not available through elements downloads, but the item will continue to work regardless of submitting this.
