Can not see videos on you tube?

I'm having problems viewing videos on you tube, This is what I see: I can here sound from the videos but the video doesn't show, but yet at the same time I can share the video on facebook and it plays fine, Also while viewing videos from you tube when the progress bar is moved it blurs and lags a trail where the video is supposed to be all of this happened when I updated my Flash Player but the videos work fine on facebook via after I have shared the video? If anyone can help me with this problem Ill appreciate it so much

 

I'm running windows 7, I've tried using mozilla and IE 8

 

you say that like I'm a theif or something I bought this computer and it had a bootleg version, jeez whats the big deal anyway, are you making money off of microsoft or something, am I taking food out of your mouth because I have a bootleg version, get a life man

 

A big problem with trying to help out with an illicit version of software is that we don't know whether it's malware-free or how it might have been 'doctored' to make it functional. Nothing personal, it's just the way it is.

 

Well crapola I guess I'll try a different place for some help
