For all reset of activations you need to send an email to email@example.com.
You will receive an auto-generated ticket number. In order to keep your position in the support queue do not send another email until contacted by a tech support person.
Stardock Sales and Support are open Monday - Friday (9am-4pm EST). Every effort is made to respond to queries as quickly as possible, though emails sent after-hours and on weekends will generally not be seen until the following work day.
Please note it is the weekend now.
