TemplateToaster occasionally runs "Design a Theme" contests where the prize is a lifetime unlimited license key. These are truly exclusive, as only 3 keys are issued per contest.
If you're having trouble with your activation key, the best course of action is to contact TemplateToaster's customer support directly. They can verify your purchase, assist with activation, and provide guidance based on your specific situation. templatetoaster activation key exclusive
