Sorry for the trouble here Michael. It sounds like something is going wrong specifically with your site and use case — many folks are using Event Aggregator without issue. (We have a few known bugs, but nothing like what you describe—and I cannot recreate issues like you describe myself).
1. What license key did you renew?
2. Can you share a screenshot of the screen you are on in your wp-admin where you see the message you describe here:
when I try to import it says I need to buy the Event Aggregator.
You can do so by uploading the screenshots to this thread. If you have issues with that, you can upload to Imgur.com, Flickr.com, CloudUp.com, or any similar image-hosting site; then just share the links to those images here and I’ll take a look.
I’ll take a closer look at these details and see if I can identify what’s happening.
Thanks,
George
