Each time I try to download a EPUB book to my iPhone 4 via the Overdrive app, I get this error message.....
"ACS4 Authorization Error: 2004
The only thing that has worked is deauthorizing and then reauthorizing my Adobe account, but each time I do that I get another error message....
Once I clear this error message, my books just start downloading on their own.
I have no idea what these mean, but it's getting a bit annoying to do this every time. Any suggestions?
Are you downloading directly onto the iPhone Overdrive app, or are you downloading to ADE on a computer then moving the books to Overdrive?
If the second, try using the Bluefire app on the iPhone instead of Overdrive.
It seems to be more reliable then Overdrive app; and it can read Overdrive library books (with proper authorization), but can't download them directly.
