& i did not write any alternative e- mail
Answer:
I don't think there is anything you can do there. Did you try the secret question? If you really cannot remember the password you'll have to start a new account I'm afraid. So keep trying passwords that might be true. And think of an easier one in the future of course. Sorry I can't really help you there, but I'm afraid there is no other option.
Answer:
didn´t you fill in the password-hint?
Answer:
I can say pretty sertain that if you don't remember username and password or secret answer then it is lost. Without it there is no "legal" and I've never heard of any "illegal" way to gain your own lost password.
Answer:
Use your secret answer to change the password, alternative e-mail is not important.
