You need an active subscription to update to the latest version. Your subscription includes access to all new releases, support, and the use of the Autotune configuration tool for the length of the subscription. Once your subscription expires, you'll still be able to use the version of JFBConnect you have installed and it will function just as it has.
If you want to upgrade to the latest, need support, or want to run Autotune again, you'll need to resubscribe.
I hope that helps explain,
