I'm trying to erase my authorization for adobe digital editions because the company i'm trying to read their book says it could possibly fix the issue. They have emailed me a new acsm file but I can't remove the authorization. Currently my book wont load and says there's an "unknown Permission Error". This book isn't loading on windows 10 anymore, initially it worked fine. It worked on a edge 7 android phone but no longer and it never worked on a Samsung 7 or J7 phones. Have no idea how to get this book working, very frustrating. Help.., Please?
