I received an email from Pinnacle offering an upgrade for my pctvrage tv tuner card that should have upgraded it from AVI to mpeg. All it did was stopped me from using my tuner. It couldn't find shell32.dll. I tried installing the original software but it reported card in use by other software. Obviously the upgrade had not uninstalled fully. In the end I had to fully reinstall my system in order to regain use of my tuner. Pinnacle have refused to refund until their support has investigated. Unfortunately there is not much in the way of two way dialogue on their website. So my upgrade looks like a loss for me. Has anyone else had dealings with Pinnacle? norfred.
