Hello,
I downloaded an e-book from lulu.com yesterday. It was an .acsm file, which forced me to install Adobe Digital Editions 2.0 in order to view. I installed it without authorizing and browsed the book for a few minutes then turned off the program. Later I returned to read it but there was a message about some licence key being broken or something, with E_AUTH_BAD_DEVICE_KEY_OR_PKCS12 in the error message. I tried to authorize ADE to see if it would help, but it gave me a message saying "Digital Editions encountered an error on the activation server", with the familiar E_AUTH_BAD_DEVICE_KEY_OR_PKCS12 code.
I tried removing the book from the library and reimporting it, but now it won't even do that without the same error message. I've tried deleting the .acsm file and redownloading it, unistalling ADE and reinstalling it, made sure the firewall allows acces to the internet, and keep getting the same message. I'm running on Vista. It works with DRM-free .pdf's I have, but I can't download any of the sample books on Adobe's website to test further because the server doesn't respond.
Any ideas?

I finally was able to download a .acsm file from Adobe's sample books page. It evokes the same error message. No progress.
Also, I attempted to see if I could view the file on my phone instead of my computer, but seeing as how the first (and only) time I opened the book ADE was not registered, and therefore rights were limited to that one device, it won't let me view it because of that whole DRM thing.

I noticed that you are running on Windows Vista which ADE 2.0 does NOT officially support. Have you tried any other Windows platform like Windows XP or Windows 7?

Unfortunately Vista's all I got. That could very well be the problem.

I have now corrected this error!!
at last....
I was advised that if you open Adobe Digital Editions and then press “Ctrl + Shift key and the d key” at the same time a pop up box will appear “ Erase computer authorisation” if you click the button on the right “ Erase Authorisation”.
Then the first time you use Adobe Digital Editions, you will be asked to authorise the software with your ID. Should you not receive this prompt, click ‘Help’ and ‘Authorise this Computer’
And it worked!!!

Hey,
Thank you so much for the posting. However, I attempted to erase the authorization, but it told me that it's unable to erase the authorization at the time, even though I entered the correct password. I have tried multiple times. But it's still not working. I don't why. Is there any other procedure that I have to follow in order to be able to de-authorize the Adobe Digital Editions?
Regards

If due to some reason, you are unable to deauthorize ADE, follow the below steps:
Mac: Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.
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 have an Ipad Mini 3 - I am unable to open any books that I am borrowing from my Library. I keep receiving the message:
I can download the book to read on my laptop, but the whole point of using my iPad is that its small and thus more convenient.
I'd appreciate assistance to get this corrected.
Thanks!

I have a MAC and the problem as described above with the error code and the deauthorization not working. I tried your suggestion to "
Mac: Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.
ADE will be deauthorized now."
However, that file does not exist on my computer. What can I do?!!

This deactivation.dat file doesn't exist on my Mac. And i have one of the latest version of ADE (4.5.11...).
Is there any other solution?
Thanks a lot

This worked! I'm on a mac and I could not find this file, but did a search for "activation.dat" and deleted the file in that way - I was then able to re-register and open by .acsm file.
I contacted Adobe's chat help and they basically said since it's a free product they don't provide support (they did send me a link to this page). Pretty crummy.
