okay incase u r wondering how to get online if you dont have msn or windows live messenger but have internet (very unlikely but posible)as a mater of fact i had the problem  and found out a truly amazing thing about msn or windows live mesenger it seems if your time date ,timezone etc is not correct it wont (computer time i mean the one normaly on the lower right corner of the monitor screen)so consider checking that also not just tht the whole of msn is unavailable if time aint available but it may take time for this to take affect so might not happen instantly
