I have a problem

adobe flash player is not working. when I use flash player in Internet explorer, It says you need flash player. even I have one installed. so I clicked link and tried to download new one, and adobe site says you can't download because you have flash player in your browser. I've turned off active X filtering, and turn on shock wave flash object at add on manage. can I somehow uninstall flash player and reinstall it? it's driving me crazy.
