Im not open my yahoo.messenger

i got the same problem with my ym 11 too.. but honestly looks like its ym problem that it may just work whenever it want to.. :( but try this.. open Yahoo Messenger click on "Messenger" (on top), choose "Connection Preferences" select "Connect via Proxy Server" try to log in ..
if it doesn't work put it back to the original settings, same instruction go to YM, click Messenger then Connection Preferences select "Connect directly to the Internet".. this time try to disconnect your internet connection first.. and then with your YM open enter your username & password but dont click "connect" yet.. connect to internet & log in to ym (you should click "connect on ym right after a second you are connected to the internet)

click forget password and answer the security questions
you will be provided with new password

YOUR ACCOUNT MIGHT BE COMPROMISED, PLEASE ACCESS YOUR ACCOUNT THROUGH WWW.YAHOOMAIL.COM AND SET A NEW PASSWORD,
THAT WAY, YOU CAN NOW ACCESS YOUR YM MESSENGER WITH YOUR NEW PASSWORD.
IF STILL PERSIST, PLEASE LET ME KNOW.

HAVE A GOOD DAY!

You can download version 10 on your computer and then update YM, running the setup. You cannot have 2 versions of YM on your computer.
If you want to connect to id's at a time use the following: You have to use a multi messenger registry and after you run that registry you will be able to open Yahoo Messenger how many times you want.
Here is a link for the specific registry: http://www.softpedia.com/get/Internet/Chat/Instant-Messaging/Yahoo-Multi-Messenger.shtml

On the second link scroll down and look for "AICI" and click on it to download.
If you need further assistance, just leave a comment. Cheers

I suggest you to check whether your email address and password is correct or not, by logging in at the www.yahoomail.com website, If you are able to login then your account exists and the email address and password is correct.
If it shows wrong password, try forgot password.

If you are able to login to your account in website, only you cannot login in yahoo messenger, There might be some problem in yahoo messenger, I suggest you to download the recent version of yahoo messenger and try logging in, if problem persists check your internet connectivity, Sometimes we couldn't login if there is a problem in internet connection.
There may also be problem with windows firewall settings.

And also check whether the yahoo messenger is added as exception in the windows firewall or not, If not add the yahoo messenger to exception list.

You should rely on yourself now. Take a try of this all-in-one password recovery software. It will help you recover forgotten login password for Chat Messengers like MSN Messenger, Windows LIVE Messenger, Google Talk etc. Regards!

If you have multiple yahoo ID's and wants to login with more than one yahoo ID at the same time then don't worry, you can login with more than one yahoo ID at the same time using this tip. There is no need to install any other yahoo multi messenger version, you can easily covert your normal yahoo messenger into multi messenger and enjoy your many ID's at the same time.  

Follow the given steps to change the yahoo messenger registry value:

i)Click Start button and type regedit in Run option then press  Enter:
  Here locate the location to:

ii) HKEY_CURRENT_USER/Software/Yahoo/Pager/Test

iii) Here in right side panel, right click to create a new Dword value with name Plural and give value 1

iv) Now close the registry editor and restart your computer after any changes to go into effect.

v) For signing in with new YAHOO ID open another messenger(multiple)v open as many messengers    you need.

vi) If you want to disable the multiple messenger option then again open registry editor and change         Plural value 1 to 0.


Thanking you
