YouTube Error

[Strika]

My friend has recently brought his laptop over because he has problems connecting to YouTube. He was using IE, so I thought installing FF would fix the problem. On my first attempt, YouTube worked, but then later when I tried to watch a video, it said: Http/1.1 Internal Server Error

Then afterward some videos did not even load (The whole video page)

And afterwards not even the YouTube homepage loaded. The OS on this Laptop is ironically Vista

Has anyone else ever experienced this?

PS. I have downloaded Adobe Flash Player, but still no good.

vista is not the problem, internet is.or by any chance if parental control is enabled turn it off or try installing java
