Hi Lewis,
Thanks for getting in touch!
So sorry for the confusion. Event Aggregator is actually already built into The Events Calendar. In other words, there’s no need to download or install anything new. Once you’ve purchased a license (which you have), enter the license key on the Events > Settings > Licenses screen, and that will unlock the importing features under Events > Import.
Also, if I use aggregator on more than 1 site, do I need to list them all on my license key?
Yes, as long as The Events Calendar is installed on each of those sites, you can enter the license on the Events > Settings > Licenses screen for each one.
Does this help answer your question? Please let me know. 🙂
Cheers!
Geoff
