Hi @nnyorker,
Oh shoot, so sorry for the confusion here! Event Aggregator is actually a service that is built right into The Events Calendar — in other words, no download or installation is needed.
Once you have the license key (which is sounds like you have), plug it into the Events > Settings > Licenses screen of The Events Calendar and it will activate the importing options for Event Aggregator on Events > Import.
I see you purchased Event Aggregator twice. Would you like me to refund one of them? If so, will you please let me know the Order Number of the one you would like refunded? I’d be happy to process that for you.
Cheers,
Geoff
