"Error! Check Activation" problem persists even with current version of Adobe Digital Editions 4.0

[Don_3333333]

I have tried the recommended fixes (including trying and failing to erase the existing activation, uninstalling and reinstalling Adobe Digital Editions 4.0 (today, after a complete uninstall) and still get the "Error! Check Activation" message when I try to download EPub books from my public library. I notice that when I try to save the book as a file it is listed as "which is: Adobe Content Server Message (1.7 KB)" and shows up as a 2 kb document in my downloads folder. I've tried several library books with the same outcome. Also, I can't erase the existing activation--the responses that it is unable to do so and simply suggests that I "please try after some time" which is not helpful.

If due to some reason, you are unable to deauthorize ADE, follow the below steps:

Mac:

1. Go-> Go to folder.

Go to folder dialog will appear.

2. Type   ~/Library/Application Support/Adobe/Digital Editions

drag the activation.dat file to the trash.

ADE will be deauthorized now.

Now Authorize ADE again.

ADE will be deauthorized now.

Now Authorize ADE again.

Windows:

Choose Start > Run.

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

Right-click the Adept key and choose Delete.

In the Confirm Key Delete dialog, click OK.

Your authorization will be deleted.

ADE will be deauthorized now.

Now Authorize ADE again.

I tried this fix and "HKEY_CURRENT_USER/software/Adobe/Adept was not listed.

[shreya]

then, check your authorization, is your ADE currently authorized or not ??

I tried this solution and I could not delete anything . So I still have this problem like the original poster.

Far as I can tell....  digital editions   problems are never solved...  

I've talked to the place I bought the e-books from      ..   they can't get digital edition to work.

I have tech support with Microsoft  ... they tried and they couldn't get it to work.

Adobe doesn't support digital editions...  because it's free .. I guess that's why...  t

I give up ... 

I can try to get the e-book text book.... some other way............   grrrrr
