You can continue to use the software beyond the maintenance expiration and without payment of the annual maintenance. However, free technical support will not be available and you will not be able to use maintenance releases or software upgrades that are released after the expiration date on your USB Key(s). Also, please note that compatibility with future operating systems will only be provided to the current maintenance releases. Our website allows users to download any previous releases of Ensoft software so you will always have access to the release that works with your maintenance expiration date. The pricing of maintenance renewals have small increases with time after expiration.
