just downloaded the toy story mash up and it crashes on my son's amazon fire tablet after 15 seconds in world.  The entire game crashes.

my daughter gets into the toy story world (on her Amazon's fire tablet) and there are no controls, and it then crashes. 

I have updated all tablets, made sure the textures are up to date, cleared storage to have over 4 gigs free.

turned tablet on and off again.

please advise.  This was disappointing considering my kids birthday present
