Brand new Monster blinks green continously and fan doesn't run

You may have to "force" a software install, I'm not sure how to do it, but you can call Castle and talk to tech support Monday... or maybe one of the guys who has done it will see this thread and chime in sooner :-)

Have you tried one of your other MMM's in it's place? You might be dealing with some motor/connector problem too. I believe just a MMM plugged into a motor and battery should at least "ring" the motor on power up.
