DigiElch Licenses - Overview

Starting in May 2009 we have stopped distributing DigiElch 4.5 to new users because of some problems caused by the protection system used in this version. Existing users of DigiElch 4.5 should contact us if they still need support or if they want to continue working with DigiElch 4.0. The latter differs only in the protection system but is functionally identical with DigiElch 4.5.
