Hello, and thanks for everyone's hard work!
Here's my situation: I have a PDF file of a book or general text with a creation date of 2007. I don't recall purchasing it or even downloading it, but the title is interesting and I'd like to read it. This PDF file is located at: My Documents\My Digital Editions\restore\books
Just as background: I knowingly bought my first eBook from
Kobobooks just today (13-Jan-11). It is in EPUB format and it was DRM-encoded. I wanted to cut and paste some text from this eBook and found it impossible because of the DRM, so I used Stream Recorder's excellent Python scripts (assuming that individual is the actual author), which worked splendidly.
When I tried to open the 2007 PDF file with Adobe Reader X, it opened a browser window to download Adobe Digital Edition 1.7.2. I cannot open the file with my alternate PDF readers (such as PDF-XChange, etc.) either. I installed and then launched Adobe Digital Editions 1.7.2 to read the PDF file from 2007, it gives the following error message:
Adobe DRM Error
System: 7
State: 4
Class: 15
Code: 31
Message: Error on response from server.
Scroll below or view error.log for more details.
Your Adobe software could not be activated.
HTTP error on Adobe DRM Activator request.
Adobe DRM Activator error.
Client Code: 31 - HTTP Code: 555
Fault location: 15
--- end ---
I've received this same error message about 30 times. Large numbers of unhappy Adobe Reader users get similar errors, and according to their posts, Adobe offers little or no solution or guidance on these problems unless you pay $39.99 for real support.
Then the next thing I tried was using A-PDF.com's "A-PDF Restrictions Remover", which removes read-only status and so forth, but it gave me an error message saying: "Unsupport[ed] encryption method"
So I figured I'd just cut through all the nonsense and use the Python scripts in this thread to remove the DRM and move on.
No such luck.
I'm running 32-bit XP Pro/SP3. I have 32-bit Python 2.7.1 with 32-bit PyCrypto installed. I used ineptkey_v5.0.py to successfully get adeptkey.der and I used ineptpdf8.4.50.pyw to try to unlock the file. The error I get is: "
Error -5 while decompressing data: incomplete or truncated stream". For the record, the file is 1,333 KB in size.
Now, one thing I absolutely do NOT know is if I used this same computer to download the PDF file in 2007, but my best guess is that I did. But seeing as I've never authorized this computer with ADE till today, perhaps that's moot.
So, here are my questions:
(1): How can one tell whether any given PDF file is a "PDF eBook" or not?
(2): The error message from ADE above indicates a problem related to DRM. If this PDF file from 2007 is NOT a "PDF eBook", is there some other way to remove the DRM besides the Python scripts discussed in this thread?
(3): Can anyone offer any other suggestions?
Thanks!
