The company who supported the PECT numbers and unlock codes is no longer in business. They gave support until 2012 when the unlock codes were no longer available.
We now use a USB security HASP key to operate Garment Designer 2.5. This must be plugged in whenever using the software.
You would need to purchase an upgrade for Garment Designer, as Garment Designer version 2- 2.1.3 will no longer operate.
