Msn trouble...

im having msn trouble. i click sign in, and it says that the service is unavailable. i retried like a hundred times, but to no avail. i tried going to meebo.com, but it said that my username and/or password is incorrect. i checked my email, got no notification from msn.

something thats interesting though: someone who worked in the same office as me and had access to the same computers has the exact same problem. could it have something to do with the computers in the office?
