Good morning Stephan and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the issues you have faced while attempting to upgrade our plugins.
I would love to help you with this topic.
I can see that you placed an order for the the renewal of a business license for the Events Calendar.
You are right, somehow that did not result in the license being updated accordingly.
Our apologies.
I just went ahead and fixed that for you.
Let me know how that goes.
Best regards,
Geoff B.
