George, I had the same problem and finally got it off the 3.5" floppy.
I have that software, burned on a CD. I also made a "DOS boot disk" that will work on any Pentium-etc based modern computer to allow the old Vertex software to work on the off-chance that Windows is so bogged-up it can't handle it! I can send it to you by mail, or E-mail it to you. Let me know your preference. Steve WA4BVO Trustee, KB3OKL Repeater, Clarksville MD
