Unable to sign-in to hotmail ?

Hi,
I just updated my IE 5.5 to IE 6 sp1. After that i’m unable to login to the hotmail from my PC.
I’m able to go to the www.hotmail.com and type my email a/c & password. After that IE seems loading some page and i can see the progress bar goign on. But after few seconds it stops, i can see only the blank page on my browser. On the address bar this the URL i can see

https://loginnet.passport.com/ppsecure/post.srf?lc=1033&id=2&ru=http://www.hotmail.msn.com/cgi-bin/sbox%3fttu%3d%252fcgi-bin%252fhmhome%26reason%3dncooes&tw=20&fs=1&cbid=24325&da=passport.com&kpp=2&svc=mail&msppjph=1

I reported this to Microsoft but still now there is no reponse from them. microsoft sucks.

Atleast can anyone here help me ?
Thanks in advance
Ramanan
