UPDATE:
The woman directed me to delete the "intrface.bbw" file from the directory. BIAB will recreate the file once you reopen it. All that needs to be done from there is to reassociate your drivers and MIDI compponents as you did in the initial set up.
That is *exactly* what using the Return to Factory Settings button does, you were just told how to do it manually.
Matter of fact, there are two choices in Return to Factory, the first one resets eveything BUT the MIDI/Audio setup, which is often all that is needed, the second button rebuilds that critical file and also invokes the MIDI/Audio selection wizard, this one shold be used when there are also sound related problems.
Don't know why people seem to be loathe to use of that Return to Factory Settings button, the manual removal of the intrface.bbw file is exactly the same thing. But the button is faster, you don't have to close down BB nor search for that file in the folder.
The only time I recomnmend that manual method is when BB refuses to open. If it can't open, you can't get to the Return to Factory button...
