Hi Chris,
Just one more thing I forgot to mention: If you navigate to Events > Settings > Licenses and verify that the license key for Event Aggregator has been correctly entered and saved, but the issue persists, please send us a screenshot via private reply so we can take a look.
I would also recommend you to Navigate to Events > Settings > APIs and confirm that Event Aggregator has been connected to Facebook, Meetup and any other services you intend to import from. It everything is already connected, please also take a screenshot of this and share it with me here as a private reply.
Thanks!
Patricia
