help!

Welcome to mylot After seeing this discussion, i logged to my account, giving not just the initials but the full, like xxx.yahoo.co.in and it opens, so you please check.

When it says "Full Yahoo ID" it means your FULL email address (not just your ID). If you have an issue logging in once you have typed your full Yahoo email address and correct password, it may mean that your account has been hacked and the password changed. First use the 'forgotten password' link and you should be asked to enter the answer to a security question. If that doesn't work (or you have forgotten the security question), then contact Yahoo as soon as possible.

Did you try getting a new password? There is a place on the login page to do that. This happens to me once in awhile and I just get a new password. I try to keep a list of my log in names and passwords for all the sitess I go to. Good Luck
