I cannot login to Live! Messenger on my home computer.  I DO have a valid .NET password (it says I don't).  This morning I had to reset my myspace and Yahoo! passwords due to possible phishing.  After that I cannot login to L!M or Y!M. 

The kicker?  I can login, send, and receive messages on my cell phone with the new password!!!  Just not my home computer.

Someone please, please help me before I lose my mind totally.  I know it must be a cookie/temp file/history type setting.  And I also have a Master Password set with Firefox.  I just don't know where to start!

I CAN login to Yahoo! Mail, and I CAN login to the support page for the .NET Service.  Everything is fine according to them!

did you change the password, if you have messenger store it for you without you having to put it in each time?

I had the password in, and let it auto sign-in each time.

then you need to change that password as well...untick "remember my password", input your new password and then retick "remember my password".

See if that helps.

It's still not working, I have changed my password with Live! Support and I can't login!

then it's one for the messenger support team to handle, because it probably got to do with how Windows Live Messenger connects to the server.

Still did not figure it out, but I did set up BellSouth Messenger service and it will allow me to access both my Yahoo and MSN accounts/contacts.  Will have to do for now.
