Looks like you need to have been logged into Layonara with the given CDKey (and playername?) previous to the Master Server going down to be able to access the server.
cdkey's are not tied to an account. Ie someone can use an other computer that has the game on and log in with his account name/password and play on a server. Then go back home and play again with his account.That would prevent her from getting into other servers, which she was able to do. Just can't log in on Layo. Maybe a reboot of the server machines would clear up her problem.
