Good evening Brian and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the struggles you have experienced with your license keys.
I would love to help you with this topic.
I would recommend reading the following: https://theeventscalendar.com/knowledgebase/moving-your-license-keys/
Basically, you can simply temporarily remove your existing license key from both your site and your account and re-enter it. That should fix things.
Let me know how that goes.
Best regards,
Geoff B.
