Hi,
If you are using windows 8 operating system then it will automatically re-direct your msn website to the new msn.com website which is exclusively built for windows 8 users.
However if you want to go to the older version of websites you can try the below mentioned websites
hhtp://My.msn.com
hhtp://g.msn.com
hhtp://www.msn.com
Thanks and regards
Mubarak
