Months ago I downloaded the free version (2d) of Draftsight. I am well along in a set of plans
Now it won't open. I get the "reactivation required" notice, fill in the information, click "reactivate", and instead of an email link to reactivate, it greets me with another "reactivation required" window. Repeating, yields the same window over and over.

I have read numerous posts on the web about this problem, including the suggestion to uninstall the program and download it again.
I don't want to lose the many hours of work already in my drawings, and want to proceed cautiously.

Has any other member experienced this problem with Draftsight, and how did you fix it?
