I'm a semi-newbie.  I've installed the newest NAM, and I'm using many of the features. However, I'm confounded by the Canal Add-on Module.  I selected SimGoober's canals in the NAM install, and I've included SimGoober's canal pack, and the dependencies he mentioned, in my plug-ins.  However, when I attempt to use the CAN-AM puzzle pieces, all I get are grey squares. I searched Simtropolis and the web for a tutorial, but in vain.  Maybe I'm just being thick, but can anyone point to a step-by-step explanation of how to use the CAN-AM?  It looks very cool....
