"Save as BB song" is one of the choices in the RB FILES dropdown. When you do it, RB will ask you to identify the Melody track and the Soloist track.

The only times i have been successful at this is when the song was a BB song to begin with. All MIDI BB tracks, no audio. I imported the BB song into RB, then discovered I had deleted the original BB song. I got my BB song back, but with problems. One time RB had its own idea of what the prevailing style should be so the restored BB song sounded very off.

Try importing a BB song into RB and then back again.
