SOME HOW YOU MUST ALREADY BE SIGNED IN UNDER ANOTHER YAHOO ID,OR IF YOU OPENED UP A PROGRAM THAT USES A DIFFERENT YAHOO ID. IT WILL BOOT OFF THE FIRST ONE, BECAUSE IT'S TRYING TO SIGN-IN THE SECOND YAHOO ID IN MESSENGER ESPECIALY IF YOU CHECKED THE SIGN-IN TO MESSENGER AUTOMATICALY BOX. OR SOME HOW POP-UP BLOCKER IS STOPING THE MESSENGER FROM POPING UP. IF THAT ISN'T IT THEN I DONT KNOW. SORRY!

if your computer is on a network, check your Yahoo messenger preferences for connection. ask your admin for proxy and firewall settings

There could be many things causing this problem. Make sure your regional settings are right. If all the settings are right then uninstall your messenger and install it again. Spyware and adware could also be blocking you log ons. If spyware or adware is present, then format the computer and try re-installing the messenger. A slow internet connection may also be causing this problem. You might also want to try a new account and see if that works.

Maybe the system is not compatible or if you had a old Yahoo Messenger on it you need to uninstal it.

Make sure that you have Yahoo! unblocked from your current Firewall, Antispyware, NAT software...\n\nTry what I said first, if still doesn't connect, then try visiting the link bellow and follow click on the appropriate link depending on your version and problem:\nhttp://help.yahoo.com/help/us/messenger/\n\nGood Luck

Hi,\n\nThere are 2 reasons for this as I know it from my experience.\n\n1) Cookies, Try clearing your cookies, set your adware & malware programs to do that & also you IE to do it. Though this problem is very unlikely Yahoo & MS these days are acting cranky with all their Beta's going around.\n\n2) Your firewall is definitely the culprit. Try disabling your firewall & restart the messenger service. Remember you must end the service through taksmanager first & then restart the messenger from your start menu.\n\nApart from this if all these fail then try this. Log in to your yahoo account from IE or whichever browser you are using & go to account settings. Change your password there & signout. Relogin from your browser & logout. Now restart you messenger & try it.\n\nGood luck.

you would probably have to remove the messenger program from the add/remove program and try going into the chat line again!

May be you not tick mark on the preference that always sign in to my mobile device when i exit messenger. so please tick mark on that and you always get online with your mobile. Or just go in to edit my device option and again register your device in yahoo messenger service. Hope this will beneficial to you.

you have to be logged on as administrate on your PC. and it can be several problems or issues. You need to look in Help for Yahoo Messenger and search for whatever error message you are getting to find out why.
