You have probably responded to our "noreply" email address - you should use the "Contact Us" form in the bottom of the page if you have any questions that cannot be answered via the forum.
Your purchase is awaiting email confirmation, this means you need to access the email account that belongs to the email address you used for your PayPal purchase: paypal@****.de (domain name redacted for privacy) and click the link in that email to verify that you're not using a stolen PayPal account.
Please remember to also check the Spam folder for that email account.
If you do not see the email in that account, please send an email to firstname.lastname@example.org from paypal@****.de (It is extremely important you use that specific email account) and your purchase will be unlocked.
I used the confirmation adress, but I can't answer with my paypal adress, because it's only a forwarding adress. But the domain is the same.
Please sent the key again to my registration adress or by pm.
I'd strongly recommend switching your PayPal email from a forwarder over to a real email address that you're able to login with - forwarders not only have a chance to fail (temporary software failure will cause email to be lost) but you would be unable to recover any email that was trapped by a spam filter (which, being automatic, is not foolproof).
