Hi Catherine!
It looks like you renewed an Event Tickets Plus license. Last year we started the process of transitioning customers off of “The Events Calendar: WooCommerce Tickets” to Event Tickets and Event Tickets Plus. This new pair of plugins should work almost identically to WooCommerce Tickets, but with a lots of extra features we have built in the past year.
Event Tickets is free, and you can grab both plugins on your downloads page.
If you’d like to know more about Event Tickets and Event Tickets plus, you can check out our New User Primer, but it’s all going to feel very familiar to you as a WooCommerce Tickets user.
Let me know if you need any additional help with the transition.
