MSN not working

Why don't you try aMSN, latest betas support webcam and custom emoticons along with user pictures and a bunch of fetures that you wouldn't find on any other IM application ... get it here --> aMSN 0.95 beta

You'll find that Adium is another great IM multi protocol application... I use Adiium for AIM, Yahoo and a MSN account in which only have work contacts that doesn't require things like webcam and fun stuff... aMSN is which I use for another account with friends only... Try both get Adium at

On Adium forums there's an aMSN section too so you can get more help about those applications.

Good Luck.
