If you have the Logitech SetPoint software installed you will have folders like:
C:\Program Files\Logitech\SetPointP, and/or SetPointG. Do you have those?
You can also see by clicking Start and typing setpoint, and see if it appears in the list.
If it is there, you can either uninstall it if you don't use it, or update to the latest version.
You can change the colours of the HUD stats using the Statistic Properties
