Clara HD and Adobe Digital Editions

Hi,

I have just tried to transfer my first Library book to my Clara, but when I try and read the book I get the following message

Your eReader is not authorised to open this book

This book is protected by Adobe Digital Rights Management (DRM). ....

I have so far tried the following

1. De-Authorise and re-Authorise ADE on my Kobo
2. Remove Book and Re-download it to my Kobo (using ADE)
3. Sign out of my Kobo account on my Clara and go through the setup again and then transfer the book again.

But none of this has worked anyone with any ideas?

Thanks,


Gavin,
