E_AUTH_BAD_DEVICE_KEY (macOS Mojave version 10.14)
Hi, I'm trying to open an ebook but Adobe Digital Editions won't authorize my computer.
I keep getting an activation error message.

I also deleted the activation file (.dat) because that's the advice from adobe forums.
Still, it did not work.
I also tried to follow this: Error "E_AUTH_BAD_DEVICE_KEY" | Digital Editions | Mac OS X
But as you can see, it didn't work:

I still could not get authorization because I already have "allow all applications to access this item" (in my key chain) already selected, so I really can't do anything else. I don't know who else to ask. Seems like I can no longer use Adobe Digital Editions.
This forum is my only hope because both twitter customer service and customer service on this website can't help me.
I even deleted it and downloaded both the old and new versions.
Needless to say, I downloaded Adobe Digital Editions at least 5x.
I hope anyone out there can help me.
Thanks
