I've just downloaded the MSNP-Sharp library with the aim of creating my own messaging client, however I am struggling to get the example to sign in. The code all compiles and runs, but when I provide my login details and select "Login" I almost immediately get the following SocketException:

"No connection could be made because the target machine actively refused it 64.4.9.254:1863"

I've stepped through the code and it's the messenger.Connect() function that is causing this, somewhat obviously. When I run the example I only change the login and password details. I am running Windows 7 x86 with the latest version of Windows Live Messenger.

I have tried disabling my antivirus, even going as far as to temporarily uninstall it in case that was the error.

I have also tried disabling Windows Firewall, with no luck.
