Well, I figured out how to get the desk and the PC on the same network. Nuendo sees the desk, as it’s been added to the drop down menu in the Studio Setup Page. I’ve got 32 inputs in Nuendo activated from the desk and 12 Outputs activated from Nuendo to the desk. Now when I touch the DAW button, the desk goes into that mode, which is something. Before, I couldn’t even get that button to work! But that’s as far as I’ve gotten.
I still can’t get the transport to connect. The only controller software options that come up in the software menu on the desk is Mackie for Logic and HUI for Pro Tools. 
Both of which are available in the Nuendo drop down menu. But, neither of which seems to have ANY connection to the desk. ONLY THE STUDIO LIVE option in the Nuendo drop down menu seems to have any direct connection, which is great IF I can carry all of the necessary connections needed to get a working system.
I would really appreciate some Cubase/Nuendo SPECIFIC instruction here, if anyone can help me.
Thanks.
