I think you tried to recover password by secrete question that's why locked account. If you tried to recover by email it should not locked. You should received recovery mail from forum. Did you check your spam folder if you tried to recover by email ?

I can see password has been changed on your trust wall. Now you should prove your ownership that's your account. It would be helpful if you can sign a message from your ETH address which is used before. But your post should not edited.
