Go into your Norton settings and check to see if Yahoo! Messenger is being blocked.

You might be behind a firewall so you need to check your connection. If you have a firewall then you'll need to configure it to forward to yahoo messenger.

Have you tried COMPLETELY uninstalling it and reinstalling it?  There might be a file that got broken somehow, and that might help.  That's the first thing I try when one of my IMs isn't working.

Do you have a firewall running? There is a good possibility your yahoo messenger program is being blocked, but your browser is not.

Could be the cache of your Internet browser. Clear the cache and try again. Could be they blocked your IP for any number of reasons. Could be the port that MSN Messenger uses to communicate through has been blocked by your firewall or virus software. Could be the software needs to be uninstalled, reboot the system and reinstall. It could be the BIOS on the mother board is jamming the ports or causing a redirect of ports. Maybe a program or hardware item you've recently added to the system has interfered with MSN Messenger functions. Maybe something around a hundred various "could bes" could be the problem.

1.  Try restarting your computer.  Open Yahoo messenger before you open other programs, it may be conficting with another program you have running.\n\n2.  Uninstall and reinstall Yahoo Messenger.  \n\n3.  Try a third party program (like Trillian or Qnext) and see if you can connect to Yahoo from there.  If you can, then the problem is definitely your install of Yahoo Messenger.

What is the error message you are facing?  Please be more specific about your issue.  Are you not able to connect?  Ensure that you don't have a firewall like ZoneAlarm that is blocking Yahoo Messenger.  You can also select to connect without any proxies or Firewaal.  Go to Messenger > Preferences > Connection > Select the No proxies option.  I hope that helps.

If you downloaded messenger you should of had it installed with your messenger if you selected full install.  Look at "tools" and "manage add-ons" and see if Yahoo is listed and make sure it is enabled

i think the firewall on your computer is blocking your messenger..if you do have the firewall program on your computer try to shut down it first and then try to login again to MSN if it worked so it's true that the problem cause by the firewall...
