>> Similar in concept to why I get an error about the location of my Real Tracks directory which is right where it has been since day 1 and is where BIAB put it during installation. Why do I get THAT error any time I have created a solo section?

Likely because the location is not the same one stated in the RealTracks - Preferences section. If you still have the problem, note the exact error message, as it will tell you the details of where it was looking for the file, and you can then confirm if the file is there or not. For example, if your files are in c:\bb\RealTracks and the message says "cannot find RealTrakcs in f:\MyMusic\RealTracks", you'll know that you haven't set things up correctly, and should revisit RealTracks - Preferences.

Have Fun!
