Allow other computers on your account

[Seeya]

So my computer broke. (I'm on my laptop.)
I reformatted with my friends disk and my confirmation code doesent work (the one on the back of my computer) and i havent gotten to his code yet - beside the point.

When i press the link it sends to my email when i log into my account on a different account, it says ERROR, and it doesent accept it. I just filed a ticket.

I hear this happens with a lot of other players, can we get a fix? Sort of a hastle to have to file a ticket for every computer (4) and laptop (4) in my house.
