It sounds like a strange problem...

If you re-open one of the songs on the same computer, does the Solo track show up correctly there?
Did you create the solos by using the [Custom] button in the Select Soloist dialog?
Is the Solo itself the correct solo and the patch incorrect, or is it the wrong solo as well?
If you look in the Soloist track event list, do you see patch changes where they should be (when a new solo starts)?
Which build of BB do you have installed there?
