Moving book from Computer to ereader

Make sure the computer is authorized with an explicit Adobe ID when you borrow and download the library book.

menu/Help/Authorize Computer.  See also point (1) below.

Make sure the device is authorized with the same ID.

With the device plugged in, menu/Help/Authorize Device to ADE (digital editions).

With both those done, you should be able to copy the books.

ADE2.0 does not work correctly with some devices, and for some other devices (eg Sony) it works OK except with library boooks.

See (2) below.

Sometimes ADE gets its registration/activation confused and in a semi-authorized state.

Uninstalling and reinstalling does not help.

Unfortunately, it often then gives misleading error messages about what is wrong.

A common incorrect message informs you that the ID is already in use on another computer and cannot be reused.

This can often be resolved by completely removing any authorization using ctrl-shift-D to the Library screen on ADE (cmd-shift-D if on Mac).

Restart ADE, and then reauthorize with your (old) Adobe ID.

In extreme cases on the mac, the following extra step has helped some people.  Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.

There are lots of bugs in ADE2.0 (and 2.0.1).  Try replacing ADE2.0 with the older but more reliable v1.7.2.

(You can have them both installed at once if you like.)

Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.
