I have a Macbook Pro and Nook e-reader. Used it for years fine - now can't read books on Nook. No /nook/.adobe-digital-editions file on my computer. Transferred books on Nook get "loan token not found" error and won't open. Both Mac and Nook are authorized wth matching ID. I've reinstalled ADE on my Mac.
Its a error with the file itself. Have you check to redownload the file with o other internet Browser.
Thanks for the suggestion. I downloaded it using Safari instead of my default of Chrome. Now I’m getting this new error message! Go figure.
Und which error message you get?
