Unable to read books with DRM (KOBO Libra H2O)

J'éprouve ce problème depuis très longtemps et jusqu'à maintenant j'arrivais à résoudre le problème en effaçant ADE de mes applications et en l'installant à nouveau.  Je devais aussi réinitialiser ma liseuse Kobo et l'autoriser à nouveau.  Cela demandait beaucoup de patience et de temps mais là, plus rien ne fonctionne et j'ai le sentiment qu'ADOBE nous pousse vers l'achat d'une licence à un coût mensuel récurrent et même chose pour Kobo qui nous offre des abonnements.  La solution, pour moi, sera bientôt l'achat d'une liseuse SONY.

I have had this problem for a very long time and until now I was able to solve the problem by deleting ADE from my applications and installing it again. I also had to reset my Kobo eReader and authorize it again. It required a lot of patience and time, but now nothing works and I have the feeling that ADOBE is pushing us to buy a license at a recurring monthly cost and the same thing for Kobo, which offers us subscriptions. The solution, for me, will soon be the purchase of a SONY eReading.

Same here - Kobo help centre didn't care, blamed Adobe. Tried Adobe help centre, they were no help and suggested trying community forum - "no fix planned". I've tried emailing them so will now keep fingers crossed. Has anyone else had any luck?

I am also having the same problem.  Surely there is someone with Kobo that can help with this

Same problem with the same device, contact KOBO with no help for me. They suggested to install version 3.0 ADE but my MAC does not support old version 32 bits 

Is there someone Here who have a solution

Me also. Is there anyone out there who can assist
