I have a PRO-163 scanner. I have the USB cord from radio shack, and the Scancat Lite Plus software with the frequency databases. I've followed all the directions, tried everything, and probably just screwed it all up when I tried to uninstall the driver software for the cable, and now can't seem to re-install it. Crap, I don't know if it actually un-installed or not for that matter. Arrrrrg. I've been at this for weeks and I'm about to go insane. I have windows Vista if that helps at all. I finally decided to post my own thread after slogging through all the ones I have found in hopes there is someone out there that successfuly programmed theirs and is willing to help me. Thanks.
