How to authorize my computer if I can´t remember my password and email no longer exists

I set up an Adobe ID about 4 years ago. I am now having problems opening books on my Sony Reader because they are protected by DRM.

I cannot put in my Adobe ID for authorization because first of all, that email account no longer exists. (it was blocked by Hotmail) I no longer live in the same country as when I set up the account, so the cell phone number doesn´t exist either.

I can´t access this Adobe ID in order to transfer books from Digital Editions to my Reader. To make things worse- I had to install Digital Editions again on my computer and now I can´t authorize my computer either, because of this "lost" Adobe ID.

I don´t know if anyone can help me- I´m really stuck on this one.

Thanks so much.
