Problem opening library book on ereader.

[Suppameen]

Hi!

I've just borrowed a book from my library and can open it without any problems on my desktop ADE. But when I copied to my e-reader (Kobo Glo) and try to open it there, an error message shows up saying I am not authorized to open the file, even though both my e-reader and my laptop are authorized with the same Adobe Account. I have been able to read borrowed books before, without any problems. I have tried the usual solutions: updates all programs to their newest versions, un- and re-authorized both laptop and e-reader, to no avail.

Thank you in advance for your help,

Update:

After being away for the weekend I decided to try again. I did the exact same things as I tried before: deleting and re-downloading the library book. But this time it worked. I have not run any updates or anything since the last try. Someone explain this magic to me.
