Addon Digital game key?


I got my regular key but I don´t understand how I get my addon - Digital Game Key.
When I add a Addon for the Digital Game Key (Done it for a long time ago and tried to do it again), I can´t confirm the “addon” anywhere.
Anyone know how to get the extra key?
It is on “My Account” where I add the extra key to the addon.
But I can´t see anything on “Inventory and codes”.
Tried both Internet Explorer and Comodo Dragon (Version of Chrome).
Tried to save the Backer survey and Save Account Details.

Anyone got it to work to get an extra key?
Thank you for the help.
