Problem Adding Access Keys

I have encountered a problem when I try to add my key for my factions early access event. I choose "Manage Access keys" under the "Edit Account" button, but it only allows me to view my current access rights or go back.

Am I doing something wrong? This has only happened since the recent change to the login interface.

EDIT: If it helps, I'm using a PlayNc account.

click create account or add access key when you first open up gw.exe

Ah. Thanks.
