PDF files open blank; EPUB work OK; Authorize Computer & Authorization Info. do nothing

[Guest]

Running ADE 2.0.1.78765 on Windows 7 Pro ...

I can download ePUB and PDF files from my university library just fine;EPUB books workin just fine,  but the PDF files are completely blank EXCEPT for the contents list.

The files are, by their size, clearly not blank ... there must be some security feature stopping me from reading them.

Also, when I click Authorize Computer or Authorization Info. nothing happens.

Same as when I press Ctrl+Shift+U or Ctrl+Shift+I.

Help!!!

Can you please try with the latest version of ADE 4.0.3 Download | Adobe Digital Editions.

The menu items "Authorize Computer or Authorization Info" or "Ctrl+Shift+U or Ctrl+Shift+I" works when you are in Library mode. If you are in Reading mode, please click Library button to switch to Library mode.

Thanks for those tips.

I have downloaded and installed the latest version and chosen to 'authorize' an Adobe ID.

Behaviour remains the same. The ePUB version of the book downloads and works just fine; the PDF downloads and is blank aside from the contents pane.

The reason I want the PDF to work is because it is paginated as per the hard copy book; the ePUB's pagination is variable and so useless for referencing.

I see a lot of people have similar issues, invariably unsolved, so yet another pothole on the great Information Super Highway! Sigh.

Hello,

Have you finally found a way of reading those books in pdf ? I have the exact same problem (but on Mac), and I can't seem to find a solution...

Thanks !
