Every time I connect a synth, I get an error that the audio engine stopped unexpectedly. Normally I dismiss the error message and most of the time it works ok after that. It's pointing to a problem of some kind, but since it works, I get to wqork instead of investigating something I have no idea how to fix. But with one of my synths, after I connect it, and get and dismiss the audio engine error, then when I try to load an instrument into it I get a different error message that the Teleport Server has stopped working. After that, nothing seems to work at all, and pretty soon Sonar crashes. What is going on here?
