Adobe ID not working

Re-posted as case shut down in 2 min when I walked away from my lappy; sooooo frustating when waited so long for somebody to reply 

  I use Sony e-reader for my e-books.  Suddenly, last week I'm unable to download.  I'll sometimes be able to download book but it won't transfer into my Sony e-reader.

Apparently in Adobe Digital Editions, whenever I type in my Adobe ID & password, it replies every time "activation server error."  I'd just reset my password again & still same message regarding error.  Why am I having such difficulty ?!?!?!

Windows:

    Close all applications.
    Press WINDOWS + R.
    In the Open text box, type regedit and then press Enter. The Registry Editor opens.
    In the left pane of the Registry Editor, locate the following registry key: HKEY_CURRENT_USER\Software\Adobe\Adept
    Remove the Adept Folder.
    In the Confirm Key Delete dialog, click OK.
    Close the Registry Editor.
    Open Adobe Digital Editions and reauthorize..

Macintosh:

    quit Adobe Digital Editions.
    Navigate to /Users/Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.
    If you are using 10.7, see https://helpx.adobe.com/x-productkb/global/access-hidden-user-library-files.html
    Open Adobe Digital Editions and reauthorize.

Hi Nanaky !  I'd tried all your steps above, but whenever I log into Adobe Digital Editions to authorize my Sony e-reader with my Adobe ID & password, it replies back "Digital Editions encountered an error on the activation server" every time

Has you try it with Sony for PC/Mac?

Hi Nanaky !  Yes, I'd been trying with my Sony & Kobo Glo via my PC since last week; still unsuccessful after hours & days of trying.  The ADE doesn't recognize my Adobe ID/password, despite multiple password changes too. I'd didn't have any problems till last week; nothing changed on my end nor any changes made too.  Is it possible that anybody can try to see via TeamViewer from your Help Support team ?
