I'd be most grateful if someone could lend a hand.
I've set my MAC up, which cleared the authorisation failure, however, I changed the NFPS, Rocket and IKS66 urns to the ones in the advice PDF and now I get this; <urnopen error [err No7] no address associated with host name. I've changed the NFPS one back to what I think it may have been by copying an url from the advice PDF screenshot. That now shows Bad or missing serial number. I can' find a way to enter a serial number. It's frustrating as I feel I'm so close yet so far.
