Problem activating Draftsight

I downloaded and installed "DraftSight" your free Cad program. My problem is this, the computer I am using it on, is not connected to the Internet, and so I cannot activate it from within the program. Because of this, I cannot even ENTER the program, for the message box closes. Can I activate this program any other way? If anybody can offer a suggestion,v I would be glad to hear it - thanks.
