DraftSight hangs at activation

Hi,

  I just downloaded DraftSight after seeing good feedback on it on the internet.  My problem is that when I launch the application and enter my email address to activate it, DraftSight just hangs.  If I select "Activate Later", the application loads normally.  Anyone have any idea how to resolve this?

  I'm running DraftSight on Windows 7 Professional 64-bit.  My system has 2GB RAM, 500GB hard drive.

  Thanks for any help you can give.
