Are you sure they went offline immediately?  Theres an updated messenger now, maybe you should uninstall the older one and download the newer one.

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

If you dont think your computer can take it, try downloading the older version of yahoo since they take up less memory.\n\nGo to this page:\nhttp://www.oldapps.com/yahoo_messenger.htm

Does someone else use your computer? Maybe they uninstalled it. Try reinstalling whatever messenger you use.

it might be some settings u have done. perhaps u can relook at it again then see if there is a reason behind any unknown functions you have yet to know. it might be handy when u relook again.

The problem is in the messenger, first check the preferences and then alerts and sounds, check mark the appropriate alerts.\nMore, you can resinstall the messenger to enable the disabled features.\n\nhttp://360.yahoo.com/jcbroogley
