    "An invalid plug-in has been detected"...


      when I try to open a downloaded file, it then comes up on the screen, "An invalid plug-in has been detected' Adobe Reader , and then it closes the file down when I click OK or just close the box...  What does this mean and how can I correct this problem?????  HELP!!!
