Dont panic the Finderorder website only works when you bought the game from the NA store

Since your from the EU you get the code directly by mail
Ok its weird you didnt get yours yet got mine on 22 august in the early morning

But keep in mind i did 4 tickets with them about not getting my key
(yes 4, i was worried too )

Did that caused them to resend my key? maybe
Or are they just late with the key because of the amount of people?

Best thing to do is make a support ticket

Also make sure you check your spam folder and you dont have something enabled that automatic removes SPAM
For example my mailhost automaticly put SPAM mails into a seperate folder on the Webmail
So in my PC client for mails i never seen those
