Can you please confirm the ADE version you used to activate KOBO? You can download the latest version of ADE from Download | Adobe Digital Editions.
If you have the latest version, please try the below steps:
1) Install ADE 4.0.3
2) Deactivate KOBO in the device
3) Mount KOBO in ADE
4) Activate KOBO using ADE
Hope now you can open the books successfully.
I tried that, plus changing my password as suggested on Twitter DM. Nothing has helped. They suggested contacting NetGalley because the file may be corrupted. Does that happen often? I do not think that is the problem because it's been several files (from two accounts) that have not worked.
i have the same problem. Some books open some dont. Learning to dislike my kobo.
I am really exhausted with Kobo and ADE. I spent all my weekend trying the solutions given here. None worked!!!
I downloaded the ADE 3 and now am having a licence problem. Problems just follow problems.
Could you please work out this Authorised issue?
