If there is no activity in the MIDI Monitor then there is no MIDI data being received from your keyboard. To be sure, click on the Filter button in the MIDI Monitor and select 'Computer MIDI Input'. When you press keys on your Yamaha you should see the Note On events appear in realtime.

Check the Options | MIDI/Audio Driver Setup again, and make sure that you have the MIDI Input driver selected. There is only one other setting that I can think of, which is Options | Preferences | MIDI Options, make sure that Thru checkbox is selected.

You might try closing Band-in-a-Box, unplugging your MIDI Interface from your PC, plugging it back in, then try again..

Edit: I noticed you say that some other programs seem to be receiving MIDI. Are you sure it is MIDI and that you aren't recording the audio from it and thinking it's MIDI?
