My husband got his but I am still waiting on mine...
I wasn't able to find your support ticket, only a mention of your e-mail address in your husband's ticket.
I will ask one of my colleagues to send you the key in a moment.
Me and my brother bought NWN Diamond Edition, and both requested a key a while ago. My account name is knoxrub, and his is walker. Please email us the key. Thanks in advance!
As far as I can tell you sent your tickets around the time you posted this. My colleague will be finished with the keys very soon, so you can expect e-mails within the hour.
