I bought darksouls through steam on christmas sales and bound it to one of my windowsmail but now It has been months i cant recover the mail and Now that I try to play dark souls again I cant because that mail is blocked.
Problem would be solved if i could answer the questions microsoft asks me to recover the account but the problem is i dont remember saying any important mail since I dont use that email address for anything but signing up to games and newsletter. (I got another for important stuffes and work related to university).

I want to know if its possible to recover that mail address if I provide the Key product of the darksouls game i bound to the mail... and im looking for a way to contact the support
