Hi Teresa,
Thanks so much for reaching out!
I would recommend looking in the plugins folder in your FTP application. You can head over to the root directory for your WordPress installation and then go to /wp-content/plugins. Check to see you have the following two plugins installed:
- Event Tickets
- Event Tickets Plus
If they are there, and not showing up on your site, you may want to delete them from there and re-download them from your Downloads page via the manual updates process:

Let me know how that goes!
Thanks,
Jaime
