Hi Onlyrhythm,

Please

1) Install the latest program update for your version:

2) Install the latest RealTracks and RealDrums updates:

If you're still having the problem after doing so, what version and build are you using? (Click Band-in-a-Box > About Band in a Box to find this information).

Thanks,
Will
