Good evening Danny and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear that Event Tickets Plus was nowhere to be found.
I would love to help you with this topic.
I am not sure why your account did not get that automatic Event Tickets Plus license added to it, but I went ahead and added that license.
You can now find Event Tickets Plus in your downloads page as of now.
I also recommend reading the following article for a smooth transition: https://theeventscalendar.com/knowledgebase/moving-to-event-tickets-plus/
Let me know how that goes.
Best regards,
Geoff B.
