EZ Arms Keeper is upgradable when new features / bug fixes are released and your subscription is active. The upgrade process is backwards compatible with previous versions of EZ Arms Keeper.

Your Bound Book information is not affected during the upgrade process. However, it is always a good idea to make a backup of your Bound Book before performing an upgrade. Once EZ Arms Keeper is upgraded and you first open a Bound Book you will be prompted to upgrade the Bound Book at that point in time.

Simply download the trial version and install.
