I use a mac but since SignBlazer Elements/US Cutter won't work with mac a friend gave me an old Windows XP desktop to run my US Cutter. But it cannot conect to the internet and as such I cannot 'register' SignBlazer. I just need an Activation code. Can anyone please please tell me what to do? I'm about to sell the bloody cutter but it would be an awful shame. I'm really at the end of my rope with this thing.
