Long story short: Purchased video from Amazon. Used Amazon Unbox 'app' to download to my PC. It worked. Moved video to SD card via PC, worked again. Movie now on SD card in wmv format. Insert SD card to Note 10.1 (2014). DL 'My Files' app, app recognizes SD card however says " cannot play license has expired " and won't play. DL'd many more apps to convert/play etc etc and no dice. Any info is much appreciated. Thank you.
