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
Adobe Request
Error: E_ADEPT_UNKNOWN-"
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....
"Fulfill:2004
Adobe Request
Error: E_ADEPT_LIC_TOKEN_NULL_DATA-"
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?
Thanks!
