Hi,
I'm new to this forum but found it very informative. Was running 4.2.8432 and can no longer open library books, many people seem to have this issue see link below, and today Kobo told me they are aware of it and are working on a fix, so I upgraded from here to 4.3.8945 and they still didn't open so it appears it is not fixed yet?

I think there is an error in authorising the Kobo to open the DRM files even though Adobe Digital Editions says the device is authorized.
So as I knew my Kobo touch Mark 3 was working fine last year I went back to 3.19.5761 from your website and the library books will now open fine so thanks for that, but obviously I cannot access my books purchased as I would need to sync from the desktop site won't I and then will it update to the latest version again which I don't want?
So are you aware of this issue?
Thanks
