Hmm. Not sure about this stuff. I can't find the same situation on the net. Everyone who's received this error has a rooted device.

If you want to try: link. This is a link to myanimelist forum which shows how to play on a rooted device. (Though you said it isn't really rooted, I'm just leaving the link here in case you want to try.)

Let's hope someone would come and help. If all else fails, then you have no choice but to bring it to a technician.
