For some reason a few weeks back my Sonar Studio 3 stop recognizing my Midi Audio. When I go into Audio in Sonar the only drivers available are my analog drivers. I contacted M-Audio about the problem and they suggested dowloading the Windows XP Service Pack 1.

I've done that and I still can't seem to get Sonar to recognize my MIDI inputs or drivers. Yes, I've checked all cables and connections they set up correctly.

Anyone have any suggestions? It would be greatly appreciated. Thanks.
