Looking to purchase a current license version of Mach 3 sofware --- send response to rkelemen@triad.rr.com if you have a version.
If you have an old one, you have a current one. I don't understand your question...
Mach3 licenses are non-transferable. So it's illegal to use a license purchased from someone else.
