Hey Mike!
You actually have a valid license for Event Aggregator. We are in the process of retiring the Facebook Events and iCal Importer plugins and replacing them with our newest plugin, Event Aggregator.
You have been granted a license for Event Aggregator and it is set to expire on the same date your Facebook Events license expires (2017-05-07). For information, please review our Moving to Event Aggregator Knowledgebase article and if you run into any issues along the way, please create a separate thread and our support team would be happy to further investigate.
Let me know how things work out and have a pleasant rest of your day. Cheers!
