OK. Well, I'm surprised nobody bothered answering this because the answer is obvious if you're familiar with the system. Naturally, I feel a bit dumb because I didn't know what login and password to use and I didn't bother mentioning this in my post. Login with username: system and password: changeme. That solved my problem. A little like a guy calling tech support with his computer unplugged, but, eh, that's life I guess.
Later all,
