Minecraft pocket edition won't open?

Ok so heres the story:

I asked my uncle for the file of minecraft that he downloaded using his iPhone and sent it to me thru gmail so I downloaded it with my samsung galaxy fame which I had for just five months. The download was successful but when I tried opening it it kept saying "minecraft pocket edition stopped". I removed all my running apps, I restarted my phone but I still can't get into the game. I don't want to uninstall this fake one and buy the real one in the play store because my parents won't allow to buy me the game because they said it would be useless. 15 y/o girl here lol please help as soon as possible
