See if you got a yahoo messenger icon near the clock at right bottom corner, if yes, click it or right click it to see the option, make necessary change.

To save you headaches with the new version, go to this site and download version 7.0:\nhttp://www.oldapps.com/yahoo_messenger.htm

The probable cause could be you have a firewall client installed in your computer. Try disabling it before connecting to Yahoo messenger

Try to uninstall the messenger an then reinstall it. Many people including myself have encountered problems with the 7.5 version. The 7.0 version can be found here:\nhttp://www.oldversion.com/download.php?idlong=4466f0509eff95b50032209808b010af

Uninstall the one that you are using, in control panel, under, add/remove programs..Then go back to the page where you download the messenger, and get the latest version, that is available, That way, you are starting all over, and any problems, that you might have had, will be gone..It is best, always to get the latest version available..Good Luck..

Go to your control panel. Then your add/remove icon.. Click on the messenger like your going to uninstall it.. BUT,put  a check mark  on the REPAIR command.. See if that works.. if not, uninstall it and reinstall it again !

Most likely you are trying to use version 7.5 BETA which is pretty buggy and useless in my opinion. Uninstall the current yahoo and download 7.0 from here..\nhttp://www.oldapps.com/yahoo_messenger.htm

Have you tried downloading the latest version?  If not, download it from messenger.yahoo.com.\n\nIf you have just recently updated and that caused a problem, delete the program and install an older version (you can usually find this on the Yahoo Messenger website, also.  A Yahoo search can even help you find an older version, if need be.

First, I'd recommend uninstalling your Messenger and downloading and installing the newest verson from Yahoo!  When you do this, though, you might have a corrupt file in your Yahoo! Messenger directory. To fix the problem, you must manually delete the "Messenger" directory on your C: drive (default), then reinstall the Yahoo! Messenger application.\n\nTo delete the directory:\nClose the Yahoo! Messenger application if you currently have it running. Make sure all instances of Internet Explorer are closed. \nGo to your desktop and double-click "My Computer." \nClick the "C:" drive. \nGo to:\nC:&#92;Program Files&#92;Yahoo!\nHighlight the Yahoo! Messenger folder and press the Delete key on your keyboard. (All archives will be deleted if they are not copied. Please see below.)\n\nTo install:\nClose all running applications except for your Internet browser.\nVisit the Yahoo! Messenger home page.\nClick the "Download Now" button.\n\nTo copy your complete Message Archive:\nClose Yahoo! Messenger (if it is currently running). \nGo to your Desktop and double-click "My Computer." \nSelect the "C:" drive. \nGo to:\nC:&#92;Program Files&#92;Yahoo!&#92;Messenger&#92;Profiles\nYour "Profiles" folder contains your complete Message Archive. Copy it to the same location on another computer if you wish to view it elsewhere.\n\nNote: If you copy this folder to another computer, your complete Message Archive will be copied, overriding the Message Archive on the computer to which you are copying.\n-------------------------------------------------------------\nAfter that, if you still have problems, make sure that you have the latest version of Macromedia's Flash Player installed, as Messenger uses certain Flash components on startup.  \n\nBeyond that, your Yahoo! Messenger connection information may be incorrect. Follow these steps to configure your connection:\nClick the "Messenger" menu in Yahoo! Messenger and select "Connection Preferences."\nEnable the "Firewall with no proxies" option.\nSelect the correct Internet connection type and country from the pull-down menus.\nClick the "OK" button at the bottom of the window.\nYahoo! Messenger will ask you if you want to sign in again with your new proxy settings. Click the "OK" button.\nEnter your Yahoo! ID and password and click the "Sign In" button.\n\nThe above configuration works in most situations. (However, if you connect in this way, you won't be able to use the Voice feature.) If this configuration doesn't work, follow these steps:\nClick the "Messenger" menu in Yahoo! Messenger and select "Connection Preferences."\nEnable the "No network detection" option and then click the "OK" button at the bottom of the window.\nYahoo! Messenger will ask you if you want to sign in again with your new proxy settings. Click the "OK" button. \nEnter your Yahoo! ID and password and click the "Sign In" button.\n\nIf neither of the above options work, you're probably behind a firewall or proxy server that requires you to enter its address. Follow these steps:\nClick the "Messenger" menu in Yahoo! Messenger and select "Connection Preferences."\nEnable the "Use proxies" option. \nEnter your firewall or proxy server's address and port number. Contact your network administrator (if you're at work), or your Internet service provider (if you're at home) to determine the correct firewall and proxy settings.\nClick the "OK" button at the bottom of the window.\nYahoo! Messenger will ask you if you want to sign in with your new proxy settings. Click the "OK" button.\nEnter your Yahoo! ID and password and click the "Sign In" button. \n------------------------------------------------------\nIf you try all of the steps above and Yahoo! Messenger
