Hey guyz,
This new MSN Messenger (final version) is killing me. Every time I try to sign that shows me that the service is currently unavailable. When I try to use the connection troubleshooter then that says the problem is with Zone Alarm. So, I have uninstalled Zone Alarm. Still I can't sign in. I'm getting the same error message although I am not getting error message about Zone Alarm. Some times ago I installed the older version (6.2) .. that worked fine. Why MSN Messenger 7 doesn't work in my PC? What's wrong?

Please somebody help me.
