Downloaded newest version of Mach 3 from Artsoft to a thumb drive. Plugged the thumb drive into machine computer and double clicked on Mach 3. Now I have two versions of Mach 3. The old with all my configuration (licensed copy) and the new (licensed copy) with no configuration. The forum suggest that when updating, the new version would overwrite the old and configuration would be automatic. I have everyting backed-up. Little help please. Thanks
