MIDI driver problems

[I fixed this by updating the MMJ installation to 0.93 and removing the Digidesign Core Audio Plugin]

I am getting a ClassCastException when I try to run any of the MIDI libraries in Processing. I have tried with both TheMIDIBus and ProMIDI. These are in sketches that have worked perfectly in the past. Anyone have any thoughts?

System:
Mac OS X 10.5.8
Java2SE build 1.5.0_24
Processing 1.2.1

Here is the error:

ClassCastException: com.sun.media.sound.MidiInDeviceProvider$MidiInDeviceInfo
