Two things to check:

1: Are the tracks frozen? If so, transposing might not work.

2: Are there WAV or other Audio files (e.g. mp3) in the same folder as the BiaB song with the same name as the BiaB song? If so, BiaB may be playing and you might be listening to the existing audio rather than BiaB output.
