You need to find out where your RealTracks are:

- if they are in c:\bb\realtracks folder, then go into Prefs-RealTracks in Band-in-a-Box and set that as the RealTracks location.

- Regarding the "mgu is not a valid application", you need to run Band-in-a-Box, and choose File-Utilities-Associate File types, that way you can click on a song to load it. (or just open them within BB)


Have Fun!
