are you a registered owner of the program?
...or you hope to get this other persons copy working since you "might have found a dongle"?
If you have your own copy, but can't find the disc... you lost your dongle too?
I'm just curious. I paid around $2000 for Signlab 7 (or was it 8?) about 5 years ago, and had one employee who said he was really up to speed on that program, to where I thought it would be a worthwhile investment... but then he learned Flexi and it never got used...
..then as money got tight, I decided to see if I could sell it... and now I can't find the dongle... just the box, documentation & disc... I'm still hoping to find it, but also curious what you learn in this thread
