That would be Jérôme at this address: jcvdh56 @
gmail.com. He works for VDH, whereas I
am just another user, not an employee of VDH. Jérôme handles all VDH licensing issues.
Be aware that he is located in France, so take the time zone difference into account when
you start wondering whether your E-mail has been ignored. Be assured Jérôme will take
care of you as he has so many other users.
