After installing Vista I had updated everything on my system. I had tried to play some Youtube videos which failed to work. The same issue lies with Google Videos also. I am not able to understand the cause behind it. I had updated the flash player also, but still the issue is same. Can anyone here help me to get rid of the problem I am facing. I am sure there will be some way by which I can simply update the player back again and use it for watching videos.
