I post a link above on how to deactivate old activation. (reply#5) Anyway, here it is again : https://forums.stardock.com/486311/accounts-and-activation-support-faq#deactivateproduct.

As for new license not activating. Usually there is an error/typo when entering Email address while buying. You can raise support ticket using link below, use the product not receive option. Include all information details on your purchase there and Support will help you from there. Remember to record down the ticket number for future reference if needed. Do not raise multiple ticket since that will only confuse the system. Send once and wait. Ticket will be answer on first come first serve bases.
