I am not able to login despite chaning my password. I have given a 24hr prior to trying the new password. I have answered the personal information questions and it advised that I would send me details of re-setting my password to another email id, however I have not received this.

Log into what?

Sorry, forgot to mention... Cannot login to yahoo.com mail.

Tried changing password. Still does not wrk. Tried going through the process where you say "the account may have ben compromised" , it says it has sent you an email with password reset instructions The mail never arrives.

Any thoughts?

What happens when you try to log in? What message do you get? Does it tell you the password has been changed successfully? Did you use a different e-mail address when you setup your Yahoo account? Usually the reset instructions are sent to that address, not your yahoo.com one.
