K4 Mac or PC Annoying last update of app - need to reload ebooks

[brudigia]

Does anybody else have to delete all books in the library and reload them all ?
I have the message "The books could not be opened. Please remove the book from your device and redownload it"
And I do not have a small library.
This is quite upsetting, why can't the books be read again ? What has changed in the 1.10.8 ? Anybody knows ?

No, I haven't seen that. I just downloaded the new version this morning, and it appears to work exactly as before.

I just upgraded Kindle for PC App and had no problems. Others have upgraded their Android app and had no problems. You must have the Kindle for MAC App.

Has anything changed with regard to your computer's hardware recently? Did you upgrade the software or did you uninstall (saving your library) and then re-install/re-register? Or install the upgrade under a new user account (or the same account with different admin rights)?

Usually upgrading (technically installing over the old version) doesn't cause the problem you're having. But I have seen something similar happen in the above situations I mentioned. They can result in different hardware/user-based tokens being generated for the software. Which means that any books that were downloaded using previous tokens won't be readable by the new version of the software. Hence the reason for re-downloading books that are based on the new security/DRM tokens.

I haven't done anything as far as I know. I saw the message of the Kindle app which told me that the app was not longer valid and it would not start up again. So I've had to download the new app and install it, and then the problem with the ebooks appeared. Past updated did not give me this problem. I must see if anything has happened then, I have not changed any HW, of that I am sure. Something has happened a couple of weeks ago,now that I think of it, which I could not explain and I had to login again, but that was it. Uhmmm...
