I have had my Nook tablet for roughly a week and I had no problems reading CBZ files natively. Now, I get an error that states "DRP Reader Failed -- Sorry, cannot open this book." I can either close it or "Go to Wi-Fi" which does absolutely nothing. Anyone else having this problem?
Do you have Tablet or do you have Nook HD or HD+.
Nook HD and HD+ got a new update that adds Google Play Store. The comic book reader doesn't work for CBZs since there's some error added.
So you'll have to go to Google Play (look in your Apps page for the app) and download some comic reader app. If you search forums for 'cbz' then people have listed 2-3 that work well.
