I worked with DraftSight the Beta Version on my Mac. It worked perfect. In the past week it was not licensed anymore, so i decided buy this week the Proffesional version. I can't start anymore the Free Version to activate the license number. It still give 'this product is not licensed or has expired', also when i installed again the Free Version. What's the problem, how can i fix it.

with kind regards, Pieter Jukema
