Unable to open PDF: "An error occurred ..."

Hello,

I am reaching out because I have been unable to open a PDF (downloaded from Dawsonera) that is protected by DRM for some time now. However, I have all the necessary permissions...

When I try to open it with Adobe Reader, the software freezes before showing me the following error:
An error occurred during this operation. Contact an administrator if the problem persists.
(I feel like it doesn't even send a request to the DRM server!!!)

Foxit Reader indicates that it does not support this type of protection.

Thank you for your help

Configuration: Windows 7 / Firefox 25.0
