My yahoo is not opening?computer repair

Go to yahoo messenger perferences %26gt;%26gt;%26gt; Connection %26gt;%26gt; %26gt; set it to No Proxies %26 try loging in again...

If it does not work even after that then set the same connection steeings to %26gt; no network detection.

I bet it will work!

%26 even then if it dosent work, try logging in with some other ID temporarily....as its quiet possible ~Yahoo Mess Servers r down lots of time!
