This article concerns receiving email (from D16's servers) with serial number(s) of the product(s) you purchased.
After buying anything in our online shop, you're supposed to receive (chronologically) email with confirmation of placing an order sent by Fastspring. And shortly after email generated by our servers with serial number(s) of the product(s) you bought with instructions how to register in User Area and download them.
If You haven't received Your serial numbers via email, there could be several reasons of that:
Payment was not successfully completed.
In this case, you should see a message about the payment failure when placing your order, followed by an email informing you that the payment could not be processed. This can happen for several reasons, such as exceeding your credit card limit or having insufficient funds in your account.
Wire transfer selected as the payment method.
If you chose a wire transfer, the transaction may take up to a week to complete (i.e., for the funds to be withdrawn and received). Serial numbers are sent only after the payment has been finalized.
iDEAL selected as the payment method.
This type of payment is usually processed instantly; however, in some cases, it may take from a few hours up to one business day.
Email marked as spam.
Sometimes emails sent by our system may be filtered as spam or rejected by your email provider. Please check your spam/junk folder and review your email filter settings.
Incorrect email address.
If none of the above applies, it’s possible that the email address entered during purchase contained a typo or was auto-filled incorrectly. Please check any alternative email accounts you may have used.
If you still cannot find the email, please submit a ticket at http://helpdesk.d16.pl/tickets,
we will resend your serial numbers manually.
If you purchased D16 software at one of our distributors you need to contact their staff in order to receive serial number, which is basis for registration at User Area.
