File name to title field script stopped working

[twriterext]

I have Bridge CS3 (v. 2.1.1.9) installed on a 64 bit Dell Latitude E6520 laptop with i5 processor, 8 GB RAM, Win 7/Pro SP 1.  I have the "Write filename to IPTC title field" script installed in the Bridge Startup Scripts folder:

AdobeLibrary1.jsx
AdobeLibrary2.jsx
AdobeLibrary3.jsx
setfilenametotitle.jsx

The script was working but has now stopped working.  I thought it might be because I was trying to use it with raw files (NEF).  However, it also does not work with jpg files anymore - I tried it on a jpg from a different camera.

I deleted the script files from the Startup Scripts folder, ran a registry cleaner (which didn't find any leftover files), downloaded and installed the script again.  It still does not work - even after restarting the computer.

Can anyone help?
