Need For Speed: Most Wanted android Error

I bought the game from Google play a while ago. Today, I noticed an update and decided to download it again. I downloaded the 13 mb app from Google play and opened it. Normally it should start to download the game data. But not today! I opened it and after a few seconds it said on the screen "This application is not authorized for use on your Android device" and the app closed! What do I do?! Thx in advance!
