yahoo mail sign in problem

I've faced this problem gazillion times. First of all you should relax, it is not a big deal. Accounts get blocked due to several reasons pertaining to security or faulty insertion of your account details. Sometimes it happens that the account is blocked because there is some server problem which unblocks after 24-48 hours. Now as you have mentioned that you have entered your account details several times. Now let me tell you, you are been given a chance to enter your account details only 5 times. If you are entering faulty details then you had it my friend. At that point of time he will be asking you the question’s answer that you had selected when you had made your ID. Now the only hope will be that you remember the answer, if that does not happen then,you can refer to yahoo help documents or you will be sent you password details on the ID which you have submitted as an alternate ID during the creation of the yahoo mail ID. I hope your problem are resolved.
