Two quick things. 1) Pay no attention to "...Under midi/audio driver set up in the upper right corner. It says coyote wave table DXI" Once you check the two boxs below that BIAB will only use what you have selected in the box under the checks " VSTI/DXI Synth [synth font: VSTsynth font64"
2) sounds like you have the The VST synth GUI open ("grey GUI"). So now you need to select a Sound Font file. HIt the "open soundfont" button and point it to the BIAB SF file. BIAB provides options for this in C:\bb\data\libx64. If you want the the Coyote Forte GM.sf2 I would need to send this to you.

If this works now the VSTSynth will become your Default synth for all midi. You will see this in the slot 1 of the mixer for every track.
