Are you saying you have selected one of the other staves, but don't hear sound when you press a MIDI key? How about if you enter a note normally?
My guess is you have installed a nonstandard soundfont that either uses different instrument mappins or that requires custom settings for the single note dynamics controls. If that is the case, please ask for help on the Soundfonts forum and let people know which soundfont it is, and what settings you have in View / Synthesizer / Dynamics.
