Hi, Ben
Licence.txt, Is just a text file not a license.
MachLic.data-file, Removes the 500 or 1000 line limit from Mach depending on version and turns on some other items, I don't have a list.
LazyLic.data-file, Removes the 50 line limit on later ver's of LazyCam and allows offseting, pocketing and turn features.
Don't now why it's working on one computer and not the other, there was some cross ups with ver numbers a while back.
Current ver are 2.56 for Both now.
Thanks, Chip
