My Norton Internet Security 2003 has just thrown a spasm and won't let me use it; it believes that I'm not the supervisor, even though I'm the only person who has ever used my computer, and I have never set up accounts with NIS. I can still use the internet, but can't access MSN, AIM, ICQ, GMail, or Outlook Express, and I can't uninstall NIS because only supervisors can do that! I have tried RNav2003, but that seems to have failed. Can anyone help me? Please!
