well, its more likely to happen if u got a firewall rather than getting rid of one.
.... still need some more info - is it a beta version, do u have a firewall, did something change, did u install something??? there has to be something that messed up the connection enough for msn not to be able to connect. All I have now is a picture of a working computer that should run everything just fine.
Happiness is not about being perfect.
It is about seeing beyond the imperfections.
