That most probably because when you do the Start11, some error on your email address happened. It might be a typo on the email address. No worries. You can raise a support ticket using the link below. Use the product not receive section. Include all details in there. And Support will help you from there. It will take sometimes, since Support will have to go through the tickets by their orders.
Thank you,
