I have some trouble viewing youtube lately but before that, I can view to any youtube videos and other flash images. Lately, I been seeing this viewing on youtube. I got downloaded the installer many times and installed it many times too. All went good in a moment, I can view videos but after sometimes I will view another video, it goes on the error again. It is on and off, i can view and not. Please help. I am using firefox and flock browsers.
