Thanks

Updated to 6.3.6a.

Confirmed to work with ADE version 2.01.
Confirmed to work with K4PC version 1.14.0 (43019), latest as of Jan 18, 2016.
oboK installed, but not tested. I normally don't use the Kobo application.

My observation from reading a number of Alf posts over the last number of days is that decryption isn't working with particular Amazon purchases. It seems that Amazon may have changed something or other and the tools aren't working .....

I just downloaded a book using 1.13.1 and drm was removed. I thought I updated recently and was on 1.14, but I guess not. I'll have to update soon then.

This is the book - I think it has drm. http://www.amazon.com/gp/product/B013EW2SV4

You should be at ver 1.14.1 or higher, here is the little reminder I get with K4PC.

My K4PC is still on V1.12.2 and a DRM book I got yesterday (freebie) worked. But Paul tested the newest version of K4Mac and the tools didn't work.

Edit
Here's one comment:
"No way to get DRM removed. Tried Kindle 1.15, 1.14, 1.13, with no success.
I get the same error about default key…
Seems that Amazon changed some parts of the algorithm…"

Have that problem with some of my recent purchases.

I got that message last week or so when 1.14 was out and I thought I updated, but I guess it didn't work. Either that or I don't know what I'm doing.

JSWolf · 03-08-2016, 06:00 PM

I got the message about updating. I won't do it until I actually have to. I'm on 1.12.2.

pdurrant · 03-09-2016, 01:59 AM

It does seem that Amazon changed something in recent (1.13+?) versions of Kindle for Mac, and possibly Kindle for PC, so that the decryption key cannot be obtained for new installations of Kindle for Mac.

Is there any risk in upgrading an existing K4PC installation, or is this a problem that's only affecting new installations?

At the risk of getting into details that we're not allowed to do, it does seem to only affect new installations at the moment. Updates to old installations seem to keep the same key.

HarryT · 03-09-2016, 03:05 AM

Thanks, that's what I thought. Yes, upgrading clearly must keep the same key because you can still read books you downloaded prior to the upgrade. An upgrade which forced you to redownload all your books would be a real pain!

It should be fairly simple for the upgrade to re-encrypt existing books.
Even easier for the new software to read both encryption types and just download any new books with the new method.

When I first updated to K4Mac 1.13, Alf was unhappy, but doing a clean install of K4Mac 1.13 made Alf happy again.

Also, I found Amazon moved stuff around. My content is now in: Users > Home > Library > Application Support > Kindle > My Kindle Content

In K4Mac 1.12.x and earlier, my content was in Users > Home > Library > Containers > com.amazon.Kindle > Data > Library > My Kindle Content

Haven't updated to 1.14 or 1.15, and now I'm afraid to

So far, I haven't had any problems.
