Registering Darkest Hour

[Arthinas]

I bought Darkest Hour on GOG and I have a key for it, but I can't seem to actually register the key. Entering the key brings up a drop-down menu asking me to select the game I want to register, but there's no entry for Darkest Hour.

Weird. Maybe you already registered DH and that's why it's not in the select dropbox?
