Howdy fitness360,
You can freely move your license from site-to-site, even if the old one is deleted. Do you see in the upper right hand corner of this screen the drop-down menu “Account Central”? If you hover over that then click on License Keys, you should see your license and the old site it is attached to. Click “Disconnect Now” to remove the connection to the old site’s url. You should now be able to register the license with your new URL normally, just like you did with the old test site from your WP-Admin area.
By the way I removed the mention of your license key # from your post. It is generally safest to not post those keys on a public forum.
Please let me know if that works. Thanks!
