Emax

Hello,
I have an old program from 1995 for Atari.
Its called Wavemax from Soft Arts
Its a Voice-synthesis program for Emu systems Emax 2
Its also a full remote sysex-editor for Emax 2,you can control all
parameters from the Emax on the Atari...and lots more

I BOUGHT this program.
I need to make a backup copy from it ,because the disk is getting old.
But all my copied disk -images ,dont work.
it says""please insert original disk""
How do i make a disk-image (or copy) from a protected disk?

Soft Arts are long gone now,and i want to use this program for a very
long time.

What software do i need?...Thanks
Ron
