It states that Bridge not on the system but it is there and working?
Be sure to have the latest updates for both OSX and Bridge. restart Bridge holding down option key and choose reset preferences, hit ok and try again. If it works set your Bridge prefs again to custom wishes because they have been reset to factory defaults.
I have tried that one but it didn't work.
First open Bridge preferences and see under the chapter start up scripts if the scripts for PS and Indesign are present and have a checkmark in front. If no checkmark select them to activate and try again. If no script at all:
Try to find and delete the plist file for Bridge:
Quit Bridge and all other CS apps.
Go to the user library (by default hidden per OSX 10.7, use menu go and press option to reveal it.
In the folder preferences find the file: 'com.adobe.bridge5.plist" and drag this file to the trash.
Again restart Bridge holding down option key and again choose reset prefs.
Then try again.
