Are you trying to load a soundfont bank *directly*?

The bank itself needs a VSTi designed to play soundfont banks. SFZ is one such program. That program should get loaded into the slot in BB and then the SFZ control panel must be opened and from there the soundfont bank of choice should get loaded into SFZ.

Please forgive if I'm on the wrong track here, just trying to help out from data given above...
