Hi Ray, Welcome to the Forum
Your problem sounds like a defective driver installation and you are not the first to experience such problems.
I suggest you uninstall all the KN software and then re-install.
You will find a complete 'walk-through' of the process on the 'Tech Tips' page of my website. http://mysite.freeserve.com/willumspages/index.html
Hope this helps
