Good morning Jay and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
I would love to help you with this topic.
Based on the message you have been getting, it sounds like this is not a license issue as much as a glitch on our update server.
If the issue has not been resolved by now, here is what I would recommend:
- Deactivate and deleteĀ the Events Calendar Pro (it is completely safe)
- Head over to https://theeventscalendar.com/my-account/downloads/ and grab a copy of the latest version of the Events Calendar Pro
- Install the .zip file using WordPress’ built-inĀ Add new plugin interface
Let me know how that goes.
Best regards,
Geoff B.
