There is a big banner on top of your Client Area with instructions on how to unlock your purchase if you did not receive your authorisation email. Send an email to confirmation@dragonbyte-tech.com from the email address used with your PayPal purchase and your purchase will be unlocked within 1 hour.
The instructions are shown to you directly after you complete your purchase, and can be found on that very same page every time you check whether your products have been unlocked.
Any feedback you can give on how we can make this process any clearer to our customers would be greatly appreciated
