Can you log in to your Yahoo email or any other Yahoo product? If so, your password has not been changed. \n\nOtherwise, best thing to do is contact the Yahoo help desk and get them to re-set your password for you. Not sure what their policy on this is though.

Well if u r using any firewall then plz turn it of and then try.\nIf then also it doesn't work then mail to Yahoo regarding your problem.

I think there was some slight problem with Yahoo's login pages earlier. try again, it should be ok now.

I would suggest tryingn to log in again. If that doesn't work, send an e-mail to customer support with your e-mail problem.\nIt was a good idea to post your question here as well.

do you have a valid user name and password?\n\nif you don't have a username and password, you can't log in.  If you are online (as you are now) then you can sign on.  Wireless connection or not, as long as you are having internet, it'll work.

It might be possible that someone else knows your password.\nTry changing the password for ur ID and then sign in.\nit worked for me when i faced this problem.\nI hope it does for you too.

You have it set on 5 min to make you verify your password. Go to options on Yahoo! and it will give you some options.

try the same version with different set of username and password; if it works then the username and password was not correct. If it doesnt work try with a different computer connected to the same Networking Device(router or switch or modem). If it also fails check the port used by yahooo messenger.

Try it again. I had the same problem. Once I redid it, it showed up on my desktop. From there, you can sign in. If it doesn't work, just try again. Also, try at a time when everything is not at it's busiest ie during daytime.
