My email wont sign in

Msn live has a problem,

I had it and installed the msn patch, worked well over a month or so, jsut this day, when i signed in, it wont show my contacts or when it did sign it, it will just say i have no contacts, add them.

So i didnt a freah reinstall of it, and same problem pretised, and i used my mates email, and it worked fine, it went on, so i went onto my one and it just says signing in, and nothing on form there. I have not installed any patch or mod anything

So..... All feedback welcome.....
