I have been using Draftsight on both of my MacBook Pro's for about a month without any problems. The other day when I was not connected to the internet and tried to use it, it told me the trial period had expired. And wouldn't open. Now if I try to open the software without a net connection it tells me it has failed to connect to the activation server, but when connected it tries to start normally but will only open the properties and command window and will not respond after that.

I have tried to uninstall and reinstall but still get the same problem.

Any ideas?
