knight rider online

can someone help me fix my knight rider gps. it says invalid product key and appears to have no maps installed??

I made a quick Google search and came across a link to a 'free KR GPS map update'. But...the offer expired almost ten years ago and needed a registration authorization to go with it. I know site owner Neps had one of these. Alas, I've no idea if he can be reached, even via this site's internal e-mail or not.
