The company who supported the PECT numbers and unlock codes is no longer in business as of 2009. They were still giving support for a few years following until 2012 when the unlock codes were no longer available.
Back in 2009 we had to do an upgrade due to this and due to the changes in updated operating systems. We now use a USB security HASP key, sometimes referred to as a dongle, to operate our software. This must be plugged in whenever using the software.
You would need to purchase an upgrade for Garment Designer or Stitch Painter. With the upgrade purchase you will now receive a USB security key (which has taken the place of our unlock codes) and a program installation disk.
