    Invalid plugin detected. Adobe reader will quit.

      Every time I try to open a .pdf file the following message appears:

      Invalid plug in detected. Adobe reader will quit.

       

      I have uninstalled adobe reader 9 and tried installing it again, but the message persists. What can I do to fix it?
