E_ADEPT_DOCUMENT_TYPE_UNKNOWN:

I bought this book: Mastering Xpages 2nd Edition by IBM Press and on Adobe Digital Edition ver 4.0.98786 I get the above error when downloading this book. Please advice

Me too. Big problem.
No solution provided by Adobe. This is sheer criminality. How dare Adobe prevent me from accessing something that I have bought from a completely separate vendor. I had no contract with Adobe yet they are witholding my purchase.
Disgusting.

When I open a book in Adobe Digital Editions, I get the following error: Error getting License. License Server Communication Problem: E_ADEPT_DOCUMENT_TYPE_UNKNOWN:

Hi, I bought an e-book in PDF format that uses Adobe DRM. I've created an account on adobe.com and tried downloading the book in Adobe Digital Editions on the Mac (as well as the bookstore's e-reader--logged into my Adobe account--on an Android device).
It tries to download the book but get's the following error:
Error getting License. License Server Communication Problem:

Has anyone come across this? Any guidance would be most appreciated!
Thanks!

EXPLAIN ERROR - E_ADEPT_DOCUMENT_TYPE_UNKNOWN

I am trying to open a .acsm file in Adobe Digital Editions 2.0.67532
I keep getting the error E_ADEPT_DOCUMENT_TYPE_UNKNOWN
I have searched the forum and found this question asked previosuly - but NOT answered.
I would like to know what this means and why I can't download my book.
Very frustrating to try and access customer support from adobe to be thrown over to a forum which has the same questions I seek the answer to posted MONTHS ago - and they are still unanswered. There has to be an easier way!

Thanks for the suggestion, but no success - i'm guessing it's due to system restrictions at work.
I had redownloaded the .acsm file a ridiculous amount of times yesterday - i felt like my whole afternoon was a freakish deja vu loop!
I installed 1.7.2 today and attempted the download - now i get a new error message, lucky me

Annoyingly - I downloaded it at home last night using Adobe Digital Editions 2.0.67532 in about a minute. I put it in dropbox hoping i could access it today from work but to no avail thanks to security. I guess I'm just not meant to tackle this task today! Think I'll bring my laptop into the office next week and print the damn thing and be done with it.

Message; E_ADEPT_DOCUMENT_TYPE_UNKNOWN using Borrowbox.

Currently cannot borrow a library book using Borrowbox.
I get the message:
Error getting licence. Licence Server Communication Problem.
E_ADEPT_DOCUMENT_TYPE_UNKNOWN
There is no problem borrowing books from the library using Overdrive, and there was no problem when I last used Borrowbox on the 7th of September.

please make the book that you are trying to borrow is one of the below formats:
pdf, epub2, epub3.

Fulfillment Error: E_ADEPT_DOCUMENT_TYPE_UNKNOWN

I receive this error when trying to open an .acsm file on my Mac: "Error getting License. License Server Communication Problem: E_ADEPT_DOCUMENT_TYPE_UNKNOWN:" I am running Mac OS X 10.8.2. When I open the ACSM file it is in XML format and is looking for a PDF document.
What do I need to do to actually download the file? Everything else seems to be configured properly in terms of authorization.

I had the following error just today: Error getting License. License Server Communication Problem: E_ADEPT_DOCUMENT_TYPE_UNKNOWN.
I am using a Macbook Pro (2010) OS 10.10.3 and I have downloaded 100 books from KOBO using the ascm format. Usually, as soon as I click on the file in the downloads it opens up Adobe Digital Editions 2.0 and the ascm file loads into my library and opens. Not today with my 101st and 102nd books.
Having read some of the suggestions here I tried a mixture of a few suggestions and had success:
I went into the program Adobe Digital Editions 2.0 on my computer and clicked on Add to Library in the File menu. My computer immediately went to my Downloads but you may need to browse to get to downloads.
I scrolled through to find URLLink-101.ascm but at first it was greyed out and I couldn't select it. I went to the bottom of the screen and changed the Show button to ASCM files rather than PDF/EPUB which is what it had defaulted to. As soon as that was changed I could select URLLink-101.ascm and then clicked ADD at the bottom.
As soon as I had clicked ADD it downloaded straightaway into my library in Adobe Digital Editions 2.0. I then followed the same procedure with the second book I had purchased.
I have no idea why this happened after 100 other books have been downloaded normally. Weird but somewhat easily fixed for me. Hope this helps someone.

Error getting license. license server communication problem: e_adept_document_type_unknown

I began this day with ADE 17.2 and tried every proffered solution to no avail. The last suggestion was to update to ADE 3.0.
The exact error message is:
Unable to download. error getting license. license server communication problem: e_adept_document_type_unknown
I have tried completely disabling the firewall (domain, public, private) and the problem persists. I have tried running ADE as system admin with same results.
I've read all the posts on this forum and it appears no one has found a solution.
Please note: I do not have a proxy, currently all firewalls disabled, no anti-virus software used.
Windows 7 SP 1 32 bit home premium
Firefox 27.0.1
Shockwave flash 12.0.0.70
Network connection is wifi home network
Content to be downloaded is PDF from Google Play Books
Is there anyone who can offer a solution ....
UPDATE:
My husband figured out how to disable the firewall on the router and we tested again (and simultaneiously with software firewall disabled). Still didn't work.
I also created a Firewall Rule specifically for this application:
GENERAL

Action: Allow the connection

UPDATE:
I was reading other posts on similar topics and one of the suggestions was to try OverDrive. Since I already have it, I tried it and received the following error message:
The specified OverDrive media file "[local path]\AppData\Local\Temp\Seams-Unlikely-epub-2.acsm" is not valid. (The OverDrive media file root element is not valid.)
According to OverDrive's help forum that means the ACSM file can ONLY be downloaded with ADE!

UPDATE
Have learned we have a WNDR4500 router with built-in firewall which can not be disabled. On the NetGear forums, there was the uninformative suggestion to "use DMZ in the router settings" to disable the firewall. In looking at the settings for our firewall, the nearest screen I could find to resemble that suggestion contained the following:
[ ] Disable Port Scan and DoS Protection
[ ] Default DMZ Server [192.168.1.0]
[ ] Respond to Ping on Internet Port
[x] Disable IGMP Proxying
MTU Size(in bytes) 1500 bytes
NAT Filtering [x] secured [ ] open
[ ] Disable SIP ALG
I'm afraid this is beyond the scope of my understanding and have no idea what I should be doing here so have made no changes.

ADE Network requirements - License Server Communication Problem: E_ADEPT_DOCUMENT_TYPE_UNKNOWN:

Oh the joy and bliss of DRM'd training material. From my Android I can access the SAP training manual, however, from my work desktop I cannot. ADE is installed, my account activated, I have downloaded a free document (The Adventures of Sherlock Holmes). However, when I try to load the training manual, I get this error:
"Unable to download. Error getting License. License Server Communication Problem: E_ADEPT_DOCUMENT_TYPE_UNKNOWN:"
My theory is that ADE is attempting to access a server through our proxy / web content filter and is being tripped up. I would like to view some log files, understand the network requirements, etc. in order to properly formulate a request to have our network configuration adjusted to permit this content.
ADE Version 1.x had the option to turn on logging (Ctrl-Shift-T, enable logging...) however, in version 3.x, Ctrl-Shift-T does nothing.
Any help is appreciated!

It sounds like your problem is related to eBooks. Adobe Reader for iOS does not support eBooks or other types of DRM (Digital Rights Management) protected PDF documents.

ERROR GETTING LICENSE:license Server Communication Problem:E_ADEPT_USER_AUTH

Bought this book "Frontline Ukraine in epub format" from kobobooks and digital editions will not download it returning the following message:
ERROR GETTING LICENSE:license Server Communication Problem:E_ADEPT_USER_AUTH
Kobo help offer no solution.
I have and still can dowload the other book I purchased some time back using the same method.
Any suggestions as to how I might download this book would be very welcome.

Same issue for me and many others
I had version 1.7 (win 7, 64bit) working fine until this morning. Books downloaded ok from both local library using overdrive and school library using EBL. Then one *.ascm file failed to load citing an IO error on network request.
I followed the instructions at OverDrive | What to do if there is an "IO Error... and this didn't work. Same error still appeared.
Next tried upgrading to most recent version of Digital Editions, which migrated in my borrowed books and my authorisation okay. Tried clearing cache and ensuring every adblock etc still turned off, redownloaded the *.ascm and got a new Check! Activation error....
I removed my authorisation, then closed, reopened and reauthorised and then cleared files as per Overdrive link above... now getting
Unable to download
Error getting licence. Licence server communication problem.
E_Adept_Document_Type_Unknown:
Occurs with book PDF and ePub versions of the *.ascm and is very frustrating!
