Please, send an email to the support mailbox (you'll find the support email address in my signature below). Include in this e-mail your license code (not key) that you can find in this page here (once logged-in to the VWG website) + the full name of the machine on which you wish to transfer from. You will need to include a statement that you are transfering the license to a new computer, just like you told us in the post in this thread.
Please have this as the subject of the e-mail you send "Re: Need to transfer a license - LICENSING" and also include a full reference to this thread in your email.
