When I went into the midi devices tab in PT it listed the options for midi input. I noticed that the FBV control had options to load into channel 1,2,3 or 4. PT had chosen 4, which I was not aware of, but I did see that somewhere in the progression of what I was doing (can't recall now). When I tried to load it, I chose 1. I was getting an out of error message because it had already been loaded.
To program the footswitchs I went into POD Farm and right clicked on the device or knob I wanted to control, then selected midi learn, and tapped on the switch I wanted to use.
