Hi, I have IE 7.
I just had a couple of days when I couldn't watch videos and programs I have been watching for the past two months. IT WOULD TELL ME THAT I NEEDED ADOBE FLASH PLAYER 9. When I would install 9, I'd get 10, and still the videos would behave the same. JUST NOW I found a site WHERE SOMEONE ASKED after having installed Adobe Flash Player plug-in what to do because still having the problem (same thing). SOMEONE ANSWERED TO OPEN INTERNET OPTIONS (Click Tools arrow right of screen, s/b last on the drop down list), click Programs tab, click Manage Add-ons, Click Add-ons that have been used by Internet Explorer, then in the drop down, see whether Shock Wave player is enabled or disabled (enable it).
When I enabled Shockwave, RESULTS!!!! Hope this helps.
