Adium/Amsn/Mac msn/ Software Update connection errors!!!

[nuncoop]

Hello, I am having trouble using Amsn/Adium/Mac msn for some reason. My software update also does not work. I have opened console to see what is going on but I can't make sense of it. This is what I see:

*
o (process:8716): CRITICAL **: msn_session_disconnect: assertion `session->connected' failed

For the record, I can browse the web just fine. Can anyone help me?
