Dear @thezwomann,
If you use the Pro version of the plugin, please make sure to install WD Manager plugin first. You will need to log in to your account of Web-Dorado.com, then navigate to My Account > My Products page. Download WD Manager from here.
Afterwards, go to Plugins page of your WordPress dashboard and install WD Manager by uploading its package. Activate the plugin when it is uploaded.
Then go to WD Manager page and click on Plugins sub-menu item. Navigate to Purchased Plugins page and hit Reload. You will see the latest version of the plugin and can install it from this page. Note, that you will not lose any data by following these steps.
Let me know in case you have questions.
Thanks! Have a wonderful day!
