Hey Emily,
Thanks for reaching out to us! This definitely sounds like a frustrating issues so hopefully we can get to the bottom of this one quickly.
I would start here by accessing your site’s files via FTP and deleting out the current Pro plugin files. Next, download the latest version of the plugin from your account here and uploading it to your site. Then, make sure that the plugin is activated on your site.
If that doesn’t help, the next step would be to follow the Testing for Conflicts to ensure there isn’t a conflict occurring somewhere else on the site.
Let me know if this helps.
Thanks!
