An error occurred while disassociating 2005FPW.icm

I have a dual Dell monitor and Nvidia Quadro FX 4400 video card. When I tried
to delete the Dell monitor's profile 2005FPW, I kept getting this error:

An error occurred while disassociating 2005FPW.icm

This happened to three computers that uses those two Dell monitors. None of
the three computers can delete the 2005FPW profile.

Here's how I delete the profile.

Right click on desktop/choose Properties/Settings tab/click Advanced
button/Color Management tab/select the 2005FPW color profile/choose
Remove/then OK. When clicking the OK button, that's when I got the error
above.

Dell suggested that I connect the two monitors directly to the computer
instead of using DVI KVM switch. However, I don't think will make any
difference.

The reason I want to remove this profile is because I have an overlay
problem. Whenever I play my video footage in Avid NLE, the image brightness
looks okay, but as soon as I pause or stop playing, the video image looks
much darker. And so I want Nvidia's settings to take over instead of using
color management profile.

Any other suggestion is welcome.
