Registering updates
From time to time, The PandaWare Company releases free "maintenance updates" to TimeCache which fix bugs or add or refine features. If you download one of these updates, you should not need to re-enter your registration key. You should be able to simply launch the new version and resume using TimeCache as before.

NOTE: TimeCache 9.0 is a major upgrade from version 8.x, and requires a separate license. Registration keys for TimeCache 8.x and earlier do not work with TimeCache 9.0.
