DraftSight - No activation e-mail received

Hi. Great software, but I am unable to activate due to not having received an activation e-mail. I tried three different e-mail addresses and didn't receive an e-mail to any of them. I checked the junk e-mail on all of them, but nothing doing. Is there anything I can do? Are Dassault withdrawing the free license or is this just a problem with the Dassault Systemes... as it were?
