I’m curious about the termination R-Nets.
I thought they would all be the same, but there are only 38 pins on each of the connectors where the R-Nets will go, so four 10-position (9 resistor) R-Nets won’t fit. They will need a total of 40 pins. And they don’t make 9-position R-Nets from what I can see.

Ah, so there is both an easier way and a smarter way to do this.
Thanks for the advice.
It works fine now.

Bob,
It's the dreaded intermittent car noise. Take it into the mechanic and it stops making that noise.... This is why I put a life sized mechanic in the trunk... it works like a scare crow.
So, after you open KiCad, and before you click PCBNew, click File Open from the menu to open the whole project (schematic and PCB files). Then PCBNew will find the .brd file from that project folder.
Cheers,
Josh

Thanks for your help, Josh.
Here’s what I have tried:
Running KiCAD 2013-07-07 BZR 4022 – stable.
From here, I click on PCBNew and it starts.
(It complains about some unknown project – makes no sense – I just click okay.)
I click File Open, and I get a dialog saying the current board has been modified, and if I want to discard the changes.
I answer Yes.
Then I get an Open Board File dialog. In here, I navigate to where I have your files stored.
When I get there, it says No items match your search. I know for sure your files are there – I can see them in Windows Explorer.
Wait…as I am going through this to reproduce the problem, I now see where I can change the file type. And one of the types is KiCAD .brd.
I selected that and now I can open your KiCAD file.
I swear that was not there yesterday!
No more problems!

Hmm, I'm not sure why it won't open. Did you open the project from KiCad first?
Perhaps we can arrange a phone call and I can walk you through how I did it here?

Okay. I got my account straightened out on PBworks and I can get to the files.
But now the next hurdle: I cannot open any of them in KiCAD PCBNew. It wants a file with a kicad_pcb extension, of which there are none.
I have done minimal work in PCBNew, so I’m not sure what to expect.
Please advise.
