Hi,
Thanks for using our plugins. I can help out here.
I removed the license key, you do not ever need to provide that as we have it in our account.
I am not sure what you are asking.
We have this guide to moving a license:
https://theeventscalendar.com/knowledgebase/moving-your-license-keys/
And more guides for license related issues here:

Also, you can download the latest version of the Premium plugins from your account and find your license for Event Ticktets Plus there, which is different then WooCommerce Tickets.
And finally we have this guide to moving to Event Tickets Plus:

Let me know if that helps or you are looking for something else.
Thanks
