Damn you, Flash Player!

I ran across a piece of flash that claimed in needed an upgraded Flash plug-in to view it, so I went to Adobe's site and downloaded the latest version and installed it. Since that time, I've been unable to view any Flash, in any browser at my home computer. I am... frustrated.... to say the least. I need to fix this. The FAQs on the site are no help. I have uninstealled and reinstalled the player to no avail. Any suggestions?
