Thanks for replying so quickly. The authorization worked by itself eventually and I managed to get 8 out of 12 files in a row and could read them. Today I got the rest activated again by the vendor and I've downloaded the ascm files but the books won't add to my library. I'm being prompted to authorize my ADE again and I'm back to the exact same message. I can't even read the books I've already successfully got in my library! I managed to get a sample file downloaded (I picked Alice's Adventures in Wonderland) and that worked, not prompt to authorize or anything. I noticed that was an epub file though, not an ascm file, so I don't know if that's a factor. Is there any way I could use the ascm files to get epub files of my books? It'll be unusable if I'm going to fail to authorize the computer every time I launch ADE, and I need to use the books I've bought to teach classes. Should I even have to do log in every time? Shouldn't it only have to be authorized once? I've only used my ID on one computer so I'm not over-subscribed for my ID or anything and the books I've loaded successfully are still in my library, I just can't open them anymore.
Any idea would be gratefully received, thanks
It had another look around and realised that the PDF files were being saved on a network location. They moved the files to my C Drive and not only did the original 8 open without prompting, but the new acsm files I downloaded also opened! I don't know why, and neither do the IT department because nothing changed. It could be a coincidence because 8 did load the other day, but I don't know, is this how ADE is supposed to work? Basically we now have all the books we need but no idea why it works, and why it didn't! Last time it broke again after rebooting my PC, so I'll see if the files still open tomorrow. Thanks for the help so far.
Has you authorize Digital Edition as admin?
