Hello,
I’m sorry that you’ve had such a hard time getting up and running! I am not able to deregister your license from my end, as it is automatically registered when you enter it onto your site. As long as it is there, it will remain registered.
I took a look at your licenses, and it looks like only the Event Tickets Plus license is currently registered. In order to add it to your new site, you will need to follow these instructions to de-link it from your old site. Your Events Calendar Pro license is not currently linked and is good to go on your new site 🙂 However, even without having the license keys on the new site, you will still be able to upload and activate both plugins there. Once you move the license key over, you’ll be able to update automatically.
Please let me know if you run into any issues or have any questions!
Thanks,
Jennifer
