Topic: coremidi troubleshooting

Hello Everyone,
This may or may not be related to Total Mix FX but everytime I turn on/open the Fireface UCX, I get an annoying pop up window "CoreMIDI quit unexpectedly" with a very long, complex report. I've already performed numerous times with the FireFace UCX and Ableton Live8 (max 4 live) with no problems. I'm able to figure out what is different and why Ableton is crashing...I believe the problem is coming from the Fireface, because it only when that software/hardware is opened that the problem arises. Can anyone out there help me with this? Thank you, Jane
