I can't log on Windows Live Messenger after I installed Internet Security 2010

 Dear Experts,

 

        I installed the Internet security 2010 today and now I can't log onto my windows live messenger. It says it cannot log on to the internet when I choose the troubleshoot option. I use Windows XP. How can I fix this?
