Have you tried uninstalling flash, then installing the latest version?

I was getting a blank screen and video would not play. I tried URL Below in IE Explore 32bit and 64bit and video played fine. I first disabled Flash Player in Firefox went to http://www.weather.com/weather/videos/news-41/top-stories-169/cat-stares-down-mountain-lion-22257 video ! Video would still not play. So I went to control panel in Windows 7 Ultimate 64bit Programs and Features and removed Flash Player, Note there where several version, one was 10. something and the newer one 11.0.1.152. After renewing I again went to link above and was advised I needed to install Flash Player. I re-Installed from Adobe and verified that it was installed in Windows and received no video again. Note there are 2 versions installed one for 64bit and one for 32 bit but both have almost the same name. One has X64bit and the other has 64 bit. It is noted at Adobe the 64 bit contains both 32bit and 64bit install. I still can't view video after re-install in Firefox, IE 32 and 64 Fine. Same thing happens at this URL that I view all the time http://www.ky3.com/weather/ video is under Latest Video Forecast. It plays in IE fine. Videos play fine in Youtube.com thats a plus not totally stranded http://www.youtube.com/watch?v=XtMy5IBmX7E&ob=av2e Note video in IE stops when going to full screen Update 10/22/2011 IE Full Screen hit pause to play!

I have tried uninstalling and I work with Mozilla Firefox. Movies work fine on IE.
