I had installed and activated DraftSight on Windows 10. 

When Windows 10 version 1607 came along I had to reload Windows 10 version 1607 then install DraftSight but now Draftsight (free) won't activate, it stalls at the page where all my info is added.  

Is there a problem with Windows 10 version 1607 and DraftSight?  If so any work arounds?
