To anyone computer saavy. I downloaded the newest Macromedia Flashplayer, and everytime I go to a sight the requires the newest flashplayer it won't play anything for me, and says I need to download the new flashplayer.

I already did, and when I go back to macromedia's site it confirms I've already downloaded it. Why aren't any video's playing for me the require flashplayer if I already downloaded it?
