If you have purchased a license key for FUL-DISKfighter, we would have emailed you the key for the product to the email address you used in the purchase process. Please check that email account (it might take a short time to turn up), and also check your spam folder (as occasionally these emails can get filtered). If you still have not received your key after 24 hours, please contact our support folks on support@spamfighter.com
