The same thing happened to me 4 days ago. It seems Yahoo has locked me out of my primary email account. Ive had this account for more than 5 years and the username and password have never been changed, yet it tells me my password is invalid!!! Their customer service is horrendous and they refuse to give me my password (thats when they do reply every third day). My livelihood depends on information contained in my account and my life has nearly come to a standstill!! Has anyone gotten any additional help or found a way to gain access to their account?

Best of luck to us all!!!!!!!!!!!!!!!!
