unable to run performance analysis tool

I am unable to rate my laptop's performance under Windows Vista
Business because I am getting this error

Windows was unable to calculate the Windows experience index because
the user cancelled the assessment,

any ideas? (no, I'm not cancelling the assessment). The error occurs
immediately.

I get the same error and the same circumstances.
I am sure this only started after downloading and installing
the nVidia 101.41 video drivers.
