If you click on Start | Control Panel | Sounds and Audio Devices | Audio, do you have the Roland VSC selected as the audio output device? It should normally just be the MIDI device. This is just a guess.. as I haven't heard of that error before.

Do you use Finale? If so, you might want to check this forum:
