Youtube Redirecting Problem

All of a sudden when i went to log in onto youtube it gives me a redirecting problem "firefox has detected that the server is redirecting the request for this address in a way that will never complete."

So then i cleared my cookies, cache etc and try again. It works, i can browse throught youtube and watch videos. Once i sign in it gives me that redirecting thing again and can't browse youtube. Have to clear cookies etc again to browse, log in again and same exact thing happens.

I try this on internet explore, and google chrome. They all do the same!!

 

I don't know how much this will help, but check your host file in C:\WINDOWS\system32\drivers\etc.
the only line with a preceding "#" should be "127.0.0.1 localhost".

 

Nope that didn't work
