I have the same issue Gaile. As for why I did this, I had accidentally changed my display name before launch when helping my friend make an account. Going through support to see if could get it changed back They told me whenever you register a new key it will re-register your account. With this knowledge I wanted to try to use an invite a friend code to change my display name, and while this worked. I now have that upgrade to full account message in the upper left hand corner which does nothing when clicked. I seem to be able to play the game without issue. I never thought this would be an issue as I had added trial keys to the original guild wars without any problems and I believe that it will be the same here. I will see what happens in the next 3 days I guess.
