Like BMF said make sure the MIDI cable is plugged into the pedal. Look up in one of the menus for Console that's where you can edit the knobs. Like BMF I've seen this on Mac so I assume it's there in Windows too.
I've played around with the Console some but other than the relative knob positions, I don't recall that you can actually see the knob's number values change on the screen but I only played around with it briefly, maybe they change on the pedal itself.
If the knob values don't display on the computer then I'm requesting this for a future update of FL.
