Two urn:uuid, same email

New computer. I install Adobe Digital Editions 4.0 (Windows), and authorize computer using my Adobe ID (email).

But the urn:uuid is different from the one on the old computer. Both ADE have the same email. So now ! can't read my DRM books on the new computer.

So, ¿2 urn:uuid under the same email? ¿Do you know how to solve this?

Thanks,

Gabriel
