I agree with MusicStudent, there seems to be a bit of 'loop' here where you have BIAB playing your keyboard and then your keyboard playing BIAB. Problems are likely to arise if any input channels (from keyboard to BIAB) are the same as output channels (BIAB to keyboard).

In the MIDI input window, have you tried selecting "No MIDI/sound input"? What happens when this is selected. Even if you can't hear any sound from your keyboard, try playing along with "No MIDI/sound input" selected and see if the system crashes. (This will help isolate if it is the input that's causing the problem.)
