I have the right country , the right city and the right access code . I know how the encryption works and I know that finding the access code is related to finding the country and city and I got the access code exactly from the way I got the country name and the city . All is clear and logical . I cannot write here what I did because it will be a spoil . However I still do not understand why my answer is not accepted . Can anyone confirm that my answer and what I did is wrong ? because I am totally confused
