Certain resource packs or mash-ups, such as Toy Story, keep on crashing on mobile devices

I purchased Toy Story Map in the marketplace and I can't play it because after it loads on the spawn point the game crashes after around 10 seconds. I tried lowering down the settings by removing fancy graphics and chunks to a minimum but it still crashes. Can I get a refund on coins so I can purchase a different map? Or can you fix the bug for me?
