Whenever i try to sign in on windows live, with or without messenger plus downloaded, it just says 'signing in' endlessly. It isn't coming up with any error code, although occasionally it says 'cannot start a conversation with...(random contact)'. i restarted my computer(it's windows XP if that makes a difference) and re-installed windows live and messenger plus many times. The first time it worked, but then after a few days the same thing happened again and now re-installing it isn't making any difference. Can anyone help? I'm not too good with computers
