I am receiving an 'Unable to Download' error (E_ADAPT_REQUEST_EXPIRED) opening a downloaded book on my first edition Nook. Am running V2.0 on a Mac.

    Make sure the book is not genuinely expired (if a loan).

    Double-check the time and timezone settings on both the computer and the Nook.

    If neither of those works, try the older but more reliable ADE1.7.2.

    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.

    The forum software is sometimes corrupting the link above.  There shouldn't be a blank in 'editio ns.html'.  The following redirects to the same page: http://tinyurl.com/diged172

    Some people have found ADE trying to upgrade automatically. 

    It appears (not 100% sure) that if you install ADE2.0 as a new install (not as an upgrade) that your 1.7.2 will continue to run.

    Probably best to say no if 2.0.x installation asks if you want to migrate your library.

    Thank you for your help. I found that I can open a type '.epub' file with ADE but not a type '.acsm' file. I'm trying to download books from my local library to my first edition Nook and the library only offers the following download types: Kindle Book, Overdrive Read, Epub Book, PDF Book, Open Epub Book, Open PDF Book, Overdrive MP3 Audiobook, Disney Online Book.

    ADE is  silly with opening .acsm files.

    You can open them by drag-dropping from explorer or from command line (eg by associating .acsm with ADE),

    but not using the standard open command.

    Associating .acsm with ADE is usually the easiest once set up, but can be problems, see ~~~ below

    The .epub book is what you want, the .acsm is a step on the way towards getting the .epub.

    The .acsm is a sort of token file allowing download, and the .epub is the real book (encrypted for DRM books).

    ~~~

    ~~~~~~~~~~~~~~~~~~~

    Sometimes the registration of ADE to Windows as the default hander for .acsm and .epub files does not work;

    that is what causes the double-click in Explorer to fail;

    especially in Windows 8/8.1, and maybe 7;

    this appears to be a bug in Windows (for once not a bug in ADE).

    Two possible ways round it.

    First, try to force it in Explorer

    Right-click on a .epub file (and repeat entire sequence for .acsm if necessary)

    Select 'open with' if on the list, 'open' if not.

    Select 'choose default program'

    Select ADE if it is on the list,

    If not select 'more options' and navigate to the ADE executable (may be at C:\Program Files\Adobe\Adobe Digital Editions\digitaleditions.exe)

    Now .epub/.acsm files should be associated with ADE, and double-clicking should work.

    Sometimes, Windows allows you to go through all that, but then refuses to make the association you have asked for.

    In that case, the only way I know is to use a third partly file association program.

    http://www.softpedia.com/get/System/System-Miscellaneous/Types.shtml works for me.
