Thank you for your response but it still didn't work. I have tried down loading Internet explorer 9 (I have windows 7) but it doesn't seem to default and take over the existing internet explorer I have. I believe that the internet explorer on my computer is either corrupt or has missing files.
If you had IE8, and upgraded to IE9, it shouldn't need to assume default over the other version, because the other version should no longer exist. You may want to check the IE version, to verify that the IE9 installation completed. Just go to the help menu, and click on the 'about IE' option.
