Good afternoon Neil and welcome back!
Thank you for reaching out to us.
We are sorry to hear about the issues you have been dealing with while attempting to renew your license. I would love to help you with this topic.
I believe that this might be cause in part by the fact that your last order was refunded? Not sure why that is.
Would you mind trying the following link: https://theeventscalendar.com/checkout/?license_key=&variation_id=1034214&action=upgrade-renew&authtoken=
Let me know how that goes.
Best regards,
Geoff B.
