Dreaded "Error Invoking Keylight" Problem

I know this has been discussed prior, and I've read thru the various topics about this, but I think my situation is a little different...

My HP workstation, Vista 32-bit, 4 GB RAM, AE CS3, tends to fail if I either scrub or render a comp with the Keylight 1.2v8.

The footage I'm effecting is from our VeriCam, 720p 60fps DVCPRO100. It was acquired with our Panasonic AJ-1400 deck with an AJA Xena LH card into the AJA Quicktime codec.

I'm monitoring my work on an external NTSC SDI monitor from the Xena card.

That said, when I either scrub or render a clip with Keylight, I get the dreaded "An error has occurred invoking the plug-in Keylight 1.2".

But here's the rub:

If I save my AE project (which I do regularly when working with Keylight), and open it up on another workstation, it scrubs and renders fine.

I'm trying to avoid uninstalling CS3 and reinstalling (or worse yet, wiping my PC clean and starting from scratch).

Since I only seem to get regular AE errors with Keylight, and since I can render successfully on another system, I may just "live with it," since the fix may not be worth it.

Unless the fix is a simple one.

I've disabled Open GL, I tried rendering with the CAPS lock on, I've even reinstalled my video drivers and updated to the latest Keylight, but still I get (seemingly) random Keylight errors on my PC.

What I haven't tried yet is applying Keylight to non-HD VeriCam footage.

Suggestions?
