I downloaded the latest version of Draftsight 2D Free 2017 SP2 yesterday, installed it and after entering all the activation information with a good Internet connection and e-mail address, the activation screen disappears without any error messages or other information.  I have uninstalled Draftsight and downloaded it more times with the same response.  It will not activate and run.  I have done this many times on other systems before and it works just fine. This is a new system from Toshiba running Windows 7 Prof.  Any help or insight is appreciated. Thank you.
