I nerd help to recover my account

Hey guys this is quite a complex situation so I'll try being as direct as possible.

I want to access multiplayer but I don't remember the password.

I go to Aoe3's website and follow the procedure to get it back, so they send it to the associated E-mail address.

Now here's the problem, that address doesn't exist anymore; so no address, no password; no password, no account.

I tried contacting the devs' E-mails but they seem to be dead. Do any of you have some way to save the situation?
