Entering your license number does not work or is not recognised.
Early kits included a Cut2D-Laser disk with the license number printed on the disk jacket. Typing in the long license key could sometimes result in a zero and the letter 'O' or a 1 and the letter 'l' being mixed up.
Double check you are entering the correct numbers and letters.
If you are still having problems, send an email directly to Vectric Support, firstname.lastname@example.org.
