How do I fix HZTool warning: "Too many drivers!"?

[Kolgar]

After a weekend of testing new video drivers, my HZTool now gives me this message on startup: "Warning! Too many drivers detected!"

The thing is, I always perform a "clean" install every time I switch drivers, so I don't know why I'm getting this message or how I can fix it.

Any ideas? Thanks in advance!
