More often than not this is due to a typing mistake when you entered your email at the time of your initial purchase. Now that you are typing in the correct email attempting to login, without mistakes, the system does not recognize you (since it has you connected to the incorrectly typed version!).
HINT: If you never received any emails from us following your order (including your receipt) then it's a good indicator that this is the cause as well!
If this occurs, nothing to sweat! Simply SUBMIT A REQUEST to us and one of our tech support agents will be happy to make the correction for you and get you all set up properly. Please include your FULL NAME when writing in so we can more easily identify your account (since the email will be wrong!) and rectify this for you ASAP. You may submit a request directly on this page or by sending an email to firstname.lastname@example.org
