Glack, What I actually did was to create a new file with the new devices, since they are not going to interact at all with the rest of the equipment already installed. I'm here in the Bahamas, scheduled to live tomorrow in the afternoon and I don't really want to mess with what already was working fine. Actually, I haven't decide if I should update the K4 and RK3 to the lattes firmware. I'm afraid that something could go wrong and I need to be in Miami on Friday for my son's school Christmas Show.
