Problem using Bridge CS5

I have a photoshop CS5 and it works fine except Bridge CS5.

It works fine on my Mac OSX 10.5.8 but it does not work on my new Mac OS X 10.8.2.

When I try to open Bridge from photoshop CS5, error messeage appears and it says " Error2: photoshop is undefined.Line 1->photoshop invokeBridge(false,false,".

When I click Bridge icon, error messeage says " Adobe Bridge CS5 quit unexpectedly.

Thank you so much for your help.
