Getting the Activate window everytime I start DraftSight

Everytime I start DraftSight, I get prompted to activate.  I fill out the information and DraftSight starts.  If I close down DraftSight and reopen it, it prompts me again.  The next day, it prompts me again.

It's like it forgets that I activated.  There are no errors indicating an activation problem and the program does start.

Any thoughts.

Thanks in advance.
