Thanks Noel, very helpful.

Here's what it says I have:

Styles Disks : 0 (Built-in) ,1 ,2 ,3 ,7 (Country) ,16 (Blues) ,21 ,33 ,42 ,44 ,46 ,48 ,50 ,61 ,62 ,63 ,70 ,77

Soloist Disk Sets : 1 (Basic)

RealDrums sets in C:\bb\Drums\ : 1- Rock and Jazz

RealTracks sets in C:\bb\RealTracks\ : 1- RealTracks 1, 6- All Metal!, 8- Country Folk, 13- Older Jazz Swing Soloists, 14- Mainstream Swing - Jazz Rhythm Section, 48- Medium Modern Rock, 57- Jazz Swing, Laid Back

This looks a bit light on to me; but there is heaps of stuff in the C:\bb directory. Maybe I need to rebuild a database or reinstall or something.
