Quick tip: use the email address used in the purchasing process. If this does not work, then email us with your order number in the subject line and contact information in the body.
I purchased for myself: Please send us an email with your order number in the subject line, along with the your contact information.
If someone else registered you: Confirm the you are entering the same email address that was used when for the purchase. If someone else registered you, ask them for the Welcome letters or contact us to change the email address.
