I've got ADE 1.8.3 installed and authorised with my AdobeID on a 32-bit Win7 machine (on a corporate network).
I have also downloaded the three sample EPUB ebooks from (http://labs.adobe.com/downloads/digitaleditions1-8.html) without any issues.
However when I try to download the three sample PDF ebooks from that same link, I get the following error:
I also get the same error when trying to download ACSM or PDF ebooks from EBSCOHOST...
If I download EPUB sample ebooks from other sites they also open fine in ADE so it seems like a bug with specific file types.
Anyone else have this issue?
Look forward to hearing some suggesstions
ASCM's are not books, but a way to get books. Obviously a server problem to wherever you licensed the book. The ACSM is license info and points to the sites servers that run a copy Adobe Content server and request the actual book.
I Just confirmed a book from my library which uses ACS, using ADE 1.8.3.
