I got a new adobe ID with installation on new PC but eBooks are Linked to old ID

Hi there,

I have an Adobe Digital Editions (ADE) installation on an old PC (still working) and have access to all my purchased eBooks here.

The Adobe.ID is linked to my e-mail.

It is displayed as follows in ADE:

robert.locker@example.com | Adobe ID (urn: uuid: ***** 111111)

Now I install ADE on a new PC and log in with my account.

However, a different Adobe ID is now displayed.

robert.locker@example.com | Adobe ID (urn: uuid: ***** 222222)

This means I can no longer download my eBooks.

E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER

But it is the same user in both installations.

I've tries different versions and PCs. everytime the same new ID is shown.

With Verion 4.5.11 it is the same than with version 2.0

This procedure did even not help:

The technical support agent from the support chat referred to this forum.

Hope someone can help.

How do I get the old ID on the new PC?

Regards Robert
