Good evening Edward and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the fact that you are struggling with updating the Events Calendar Pro.
I would love to help you with this topic.
At this point, my recommendation would be to delete the Events Calendar Pro from your install completely and install our latest version 4.2.2.1 manually as explained here: https://theeventscalendar.com/knowledgebase/new-user-primer-the-events-calendar-and-events-calendar-pro/
Also, if you don’t mind could you please provide us with your complete system information in a private reply using the instructions found in the following link?

Best regards,
Geoff B.
