I wasn't sure where to post this one, but here goes anyway.
Up until today MSN has worked fine on this PC. Now all I get is a small window with the message "Signing into .NET Messenger service failed because the service is temporaraly unavailable. Please try again later".
I have tried loads of times but to no avail. My daughter is able to connect on her laptop as is my son on his X Box.
In Network connections the device manager says "MSN unavailable. Device missing".
I have checked firewall exceptions and MSN is checked.
What I don't understand is why only this PC is affected and not my kids.
Any ideas please.
