For the beggining try to sign in from the webinterface: Yahoo Mail. If it works, then changing connection options for your messenger. It could have changed. If it doesn't work try to reinstall Yahoo Messenger. Good luck.

Please check if you have signed in the messenger elsewhere. Normally, Yahoo messenger doesnt allow to be signed in both messenger and mailbox.

First try to uninstall and again install new Yahoo Messenger. If it still doesnt work, you have to reformat your system. It happened because your system is infected by virus which severely triggered some features of your Yahoo Messenger or maybe your Drivers.
After reformatting your system your YM will surely work.
I am expecting your comment.
