Hey there
Sorry for the confusion. You should’ve received an email containing a link to download Events Calendar Pro and the license key.
Can you go to My Account » Downloads and download the Events Calendar Pro plugin. You’ll need to keep the free The Events Calendar plugin active as well.
Then get your license key, and go to Events » Settings » Licenses to enter it.
You may have tried to do this, but in the Event Aggregator field instead. It really helps us better diagnose what might be happening when you share your System Info https://theeventscalendar.com/knowledgebase/sharing-sys-info/ with us.
Let me know if this works now.
Thanks
Courtney 🙂
