Hi Caroline,
Event Aggregator is actually a service, not a plugin. So you don’t need to download a new plugin- as long as you already have The Events Calendar. Event Aggregator is built right into TEC, and you just need to plug in your new license to activate the features.
Since you already had a license for Facebook Events, you actually got a free license for Event Aggregator. You can check it out if you’d like, or stick with the legacy importer for now.
I’ve gone ahead and refunded your purchase of Event Aggregator, so your extra license will be gone. You will see the funds back in your account in 5-10 days.
Best,
Leah
