I am running Logic Pro 9.0.2 on a Macbook Pro (10.5.8), using a Steinberg MI4 audio/MIDI interface (whose drivers & firmware are up to date). This setup works fine with all my other apps (Ableton, Reaktor, Guitar Rig, etc), but when I fire up Logic, I get the error message in the subject line. The CoreAudio preferences in Logic show 'none' for input device and nothing at all for output device. I reset the MIDI devices, just for grins, to no avail. All the plugins in my project have a line through them, even the Logic stuff like EXS24. The 'Logic Pro' menu on the apple toolbar contains items like 'About NewApplication' and 'Quit NewApplication' (!?), although the 'About' item correctly shows Logic Version 9.0.2 (1664.16). The usual 'File', 'Edit', etc.
Menus are missing. Vmware Anti-detect Patch For 6.0.2-59824. Although the loops browser works, the Library shows up as empty (hence all the missing plugins), even after I refresh the library.

Thinking that the preferences might be screwed up somehow, I removed Library/Preferences/com.apple.logic.pro.plist, which fixed everything. At least until I had to reboot for another reason. Now it gives me the same -10202 error whether or not there is a preferences file. Oddly, if I then pull the plug on the MI4, Logic tells me: 'Instrument “Steinberg MI4 MIDI” sends to a MIDI port named “Steinberg MI4 MIDI” of MIDI interface “Steinberg MI4 MIDI” which no longer exists.' So it is somehow cognizant of the device, even though no devices appear in the CoreAudio prefs. The Mac system settings default to the MI4 for input/output, and the Audio MIDI setup tool sees the MI4 w/o problem, as do all my other music apps except Logic. Unfortunately, reinstalling Logic is not an option, as I am 3000 miles from the install discs.
