Rule out the obvious first: Check the mixer to be sure the bass track isn't muted? Volume up?

More subtle: Did you enter a bass track when you typed in the chord progression, and is that what's now missing? If so, then you need to either do it on the bass track AND immediately freeze the track, OR enter it on the Melody or Soloist track (those two are the only tracks not overwritten each time the song is regenerated) and probably mute the bass track.
