eventbrite plugin is not working

We bought a license for Eventbrite Tickets personal

I am trying to input the ticket license into the plugin but it gives me the following message
Your Event Aggregator license key is invalid. Visit the Events Calendar website to check your licenses.

I am trying to create a page with eventbrite events where we can filter the eventbrite events by city and category.
We bought the eventbrite tickets personal.

Please advise on the best way of going forward! Thank you!
