Kevin,

On your video, you don't show the styles folder, to show that you have lots of style in there including the one that is not found.
And you don't show the folder tree to show that the folders are present in the same folder as bandinabox application in the applications folder.

And also, you aren't loading the song by using the file open menu command, or the song button. You are double clicking in finder. Try using file open. Because if you have multiple installations, and double click finder to launch songs, you might be opening a different installation.

Try the following.
1 launch band-in-a-box by double clicking the application from the band in a box applications folder
2 use file open menu command to load a song
3 if you get style not found look in the /applications/band-in-a-box/styles folder and see if that sty file exists (note that it is the styles folder, not the soloists folder as shown on your video)

Have Fun!
