Hi Brandon, thanks for reaching out!
All Modern tribe plugins should be running the same “dot” version. So, for example, If you are running The Events Calendar 3.12.3 (the latest), then you should be running WooCommerce Tickets 3.12 (or greater).
If you need WooCommerce 3.12, you should be able to download that by logging into the site here and heading to My Account > Downloads. If you don’t see it in there, then you may want to check that your license is active so you have access to it.
Does this help? Please let me know.
Cheers!
Geoff
