Okay, when you go to chord entry, you enter chords to 180 bars, right? Then you come back to the track screen. Do you already have ANYTHING generated and you added bars to it or is this a brand new song with nothing done yet? I ask this because is your song was 99 and you extended it, you would have to regenerate all and do a whole rewrite. I don't know where you are in the process though. I can say that I was working on one last night and did not like the ABACAB of it (my shorthand for "arrangement") and did a top down redo and then had to regenerate all to get everything to rewrite. That may not be your scenario, but just saying what I needed to do in what sounds like a similar circumstance.
