Hi all
I have 3 hotmail accounts, i sign in and i can see how much mail there is, then i go to the second sign in page, sign in then i get "page not available", i try this on all 3 accounts and 2 give me this error and 1 lets me in.
My default browser is mozilla and i'm running windows xp professional, windows live messenger version 8.1

Hope someone can help as my mail is building up but can't access it.

Thanks guys
Regards
