I have NPF 2002 installed. When I try to open NPF from my desk top, nothing happens. I have tried to uninstall it, but keep getting a message that I need a security supervisor to authorize the uninstallation. I have tried the the tutorials, but couldn't figure it out. I need to uninstall Npf because I believe it is causing to not be able to access secure portions of web sites and giving me DNS errors messages. Any help would be appreciated.
