Thanks Digi! We are a studio once again. The link was quite helpful. Here is what we followed, just short of the PT reinstall.

Troubleshooting tips

Delete Pro Tools preferences.
-Go to Users > “your user name” > Library > Preferences
-Delete 'com.digidesign.protools.plist', 'DAE Prefs' (folder), 'DigiSetup.OSX' and 'Pro Tools preferences'.
-Empty trash, then restart the computer.

Repair Permissions
-Quit Pro Tools and launch Apple's "Disk Utility" application, located in:

MacHD>Applications>Utilities.

-Select your boot drive (the whole drive, not the volume underneath the drive)
-Go to the 'First Aid' tab and select "Repair Disk Permissions"

Apple recommends doing this any time you install new software, update your OS or reinstall any software.

Databases and Volumes
-Delete the Digidesign Databases folders on the first level of all mounted hard drives, then delete the "Volumes" folder in MacHD > Library > Application Support > Digidesign > Databases.

-Empty trash, then restart the computer.
