    Problems with certificate Authentication in IE9

    Miss 'n'



      Have tried everything under the sun but Adobe Flash will not install on IE9 OR Firefox 3.6.24.

      The error is 'CERTIFICATE AUTHENTICATION FAILED'. I have tried uninstalling then reinstalling and still get the same error. ActiveX Filtering is unchecked so this is not the problem. I installed the certificate successfully but still the same error. Can anyone lend a hand here?
