Shoutbox

I have two email addresses that end in @live.co.uk and then another two that end in @hotmail.com.

Tonight, I haven't been able to sign in on either of the live ones, but I am able to sign in on both hotmail ones

My friend tried to sign onto them on her computer and they still dont work, but her @live.co.uk email addresses still work.

When I try and sign in, it just stays on the sign in page for ages, and then eventually a troubleshoot box appears, but when I scan it, there is ticks next to nearly every box, and no crosses.

Sorry if it sounds a bit confusing

Anyone able to help?
EDIT:

Ive just had the troubleshoot message up again and it says:

We were unable to sign you into Windows Live Messenger, possibly because of a problem with your Internet connection. Please try again later.
To let us try and troubleshoot the problem, click the Troubleshoot buttom.

ERROR CODE : 80072745

When I press troubleshoot there is a tick next to every box apart from IE's offline setting and Wireless. There is just a blank space next to them.


I know its not my internet though because I can sign into other accounts
