CS3 bridge runs on my laptop, but on my XP desktop it will not load - giving the error message...

An error occurred while running a script. The script may not be compatible with this version of Bridge. Check for available updates by selecting Updates command in the Help menu.

Error in C:\Program Files\Common Files\Adobe\Bridge CS3 Extensions\Adobe Version Cue Extension\VersionCue.jsx.
Line 281; app.addCustomRoot(vcRootURI);
Uncaught JavaScript exception: addCustomRoot

Hoping it would be simple, I copied the file VersionCue.jsx across from the laptop, but I still get the message.

Any thoughts would be extremely welcome. I am running CS2 on both machines.
