Hi all! I'm using DraftSight free version and I'm having a problem to activate it. When I fill in the information required (e-mail, country, title, etc) and click on 'Activate', DraftSight opens quickly, but authomatically closes. I don't have any other source to open the program, so I'm not able to use it. Do you have any idea of what should be happening? Thanks and regards,Ernesto.
