Amazon App store Says "I don't have a license for Minecraft"

I recently downloaded the 1.2.3 update from the Amazon app store. before I downloaded the update everything was fine, it would let me go into the game no problem. When I downloaded this update every time I go into the game now, it tells me I do not have a license for Minecraft and make sure I bought it from the store. I reinstalled Minecraft and reinstalled Amazon app store. Still nothing. I actually read the reviews down at the bottom and it seems that a lot more people are having this issue as well. Is there anything that can be fixed?
