I now see multiple posts dating back over a decade with reports of no response from Innolasers or the ILD SOS author for registration keys. It's been a week since my purchase. Nada. Multiple emails.
Bummer, too. I really did want to work with the program to reduce the number of points on these ilda files I'm playing with.
I guess it's not too late to file a credit card dispute and get my fiddy bucks back, but damn... I really wanted to work with that software.
