Hi Colin,
Thanks for reaching out, and I’m so sorry for the trouble here! I’d be more than glad to assist you with getting your Event Aggregator features up and running again.
To get things started, can you bring up the Licenses page of your plugin settings (under Events > Settings), delete the license key from the Event Aggregator text field, and save your changes? Once that license key has been successfully removed, you may then re-enter the key into the empty field and save again. Let me know if you’re able to perform an import again after completing these steps!
Thank you!
