Hi Greg
I am seeing that Events Calendar Pro is active for a personal license on your account until June 30, 2018.
When I view https://theeventscalendar.com/license-keys/ as your account, I can see the license key.
Just before you are due to renew, we will email you with a reminder. The other option is to renew now (6 months early) and extend the license further. This would add your payment information to your account well ahead of time.
I will investigate further to see if you can add a payment option without renewing early.
Thanks
Courtney 🙂
