PRO version 2.6.0

Hi,

I recently purchased the PRO version and today I got a message stating that there is a new version available, however automatic updates for this plugin isn’t available. I also get this message in the plugins area:

Download permission for Pinpoint Booking System WordPress Plugin (PRO version) has been revoked possibly due to a license key or subscription expiring. You can reactivate or purchase a license key from your account dashboard.

How do I go about updating to 2.6.0?
