Ice, welcome to Sevenforums!
Reseting it is a good idea. It will ask if you want to keep personal settings. After, go to get.adobe.com/flashplayer and download flashplayer to your desktop. Uninstall adobe flashplayer from contol panel in favor of installing this newer version. Check add-ons in internet explorer and make sure all the ones you want are there and none other. Having IEx64 and normal IE is standard on a x64 system, which you have. They are 2 versions of the same browser, but have about the same speed (for IE9). I'd use the normal one due to compatability reasons. Hope this helps
