Decryption Failed!

luqmaninbmore · 07-16-2010, 12:23 AM

Greetings,

I've been having problems recently accessing my Kobo purchased books. Out of the blue, I am getting the error: Decryption failed! Try resynching your library.
Resynching my library does nothing. This problem occurs with many, but not all, of the books I purchased from Kobo and synched using the Kobo app. Please don't tell me to synch with ADE or via drag and drop. I like how the Kobo format displays on the reader and would prefer to use that for the books I purchase directly from Kobo. Any ideas?

I have had this happen twice. Once I deleted and reinstalled the desktop app and all was well. The second time, it did not fix it. However, when my computer was rebooted it did fix it. (Windows Vista 32bit) It is possible that the first time I also rebooted my computer so next time, I'll try that first.

I sometimes download books via iPhone and I wondered if that was messing up the desktop app. When I have time I'll do some experimenting.

You hit it on the head. The problem was with the Desktop Client, not the reader (the books were not decrypted by the former). Reinstalling the client worked just fine.

This has happened to me again. Decryption failed.

What is it that I am doing that is causing this problem? I obtained some ePubs from my public library that I copied via ADE. These seemed fine when I unplugged my Kobo. Then I bought a new book from Kobobooks, sync'ed again, failed.

So it takes around 30 minutes to buy a new book and go through this process (some bookmarks being lost).

1) delete all my I'm Reading
2) add and "update library" in desktop -> no luck
The covers in desktop app are black for some books
Some books (not necessarily the same ones) show decryption failed
3) OK bite the bullet, delete desktop app, reinstall, redownload library
4) resync Kobo

Things appear OK now but WHAT AM I DOING? It's the third time I've had to do this???

(actually when I reopened my desktop app, some books show black covers again. I needed to quickly flip to next chapter to find my place in my book. However with no text display and covers missing, it was trial & error finding the required book)

Hi,

I have windows xp, using the Kobo desktop app syncing to a Kobo and I have tried rebooting and tried uninstalling/reinstalling the desktop app and I still get decryption failed. I have emailed Kobo help about this and have heard nothing yet.

Any other ideas?
