OK. I found my fix. Turns out it was a preference file. I created a new user and pro tools did open. So, I quickly narrowed it down to the invisible .GlobalPreferences.plist file in my user/Library/Preferences folder. Made a copy of this same file found in the new user Library/Preferences folder, changed the get info prefs to me. Put this copied file in my user/Library/Preferences folder and voila, Pro Tools opened. Only .Mac syncing and two other apps needed to be re-registered. And yes, I then installed ptle731cs3_36748.dmg a second time and all is well. I'm not sure, but I think some files in My user preference folder were bugged due to Kernel panics prior to installing this update. So, I avoided an Archive and install . Back to music making!
