Logic on life support... please help!

Question

I let my system drive get almost full (there's no audio recorded to it). While working I ignored a message warning me. This was a mistake.
Now, when loading Logic, I get this message:
Error Reading/Writing File "com.apple.logic.pro.cs"
Logical end-of-file reached during read operation
Cancel
(this 'cancel' is a button; the word is followed by some hieroglyphics)
Now all Logic plug-ins are Disabled (slash through them). No Audio will play. No motion at all on faders. Even when I try to Import Audio and have a track enabled, I get a 'you must select a track to import audio'.
My Logic is dead! Temporarily, anyway.
I took all Logic preferences out of the folders and onto the desktop and loaded Logic. No change.
I go back to Creator on Atari and I've never seen anything like this.
Any pertinent suggestions much appreciated.

Ouch!
I've seen something similar posted on a couple of other forums.. It sounds similar. When a system disk gets close to full and OSX swap files fill the drive...one of two things can happen. Logic can't write it's preference files when it shuts down or OSX swap files "possibly" overwrite existing disk files. If several other programs exhibit strange behavior, lost preferences etc...some files may have been overwritten.
The first thing to do is create some space on your system drive and delete the com.logic.pro.cs preference file and hope for the best, it will be recreated when starting Logic again.
If other preference files have been damaged look in
users/yourname/library/preferences.
Also in library/preferences.
This is the kind of inelegant behavior Logic (and OSX) could
improve upon.
