Crash with "My Life in Sakura Shores"

So today I brought the "My life in Sakura Shores" for almost $20 and I loaded into the world and everything was fine for at least a couple of minutes until my game crashed, I didn't think of it much so I joined back into the world and then not even a minute passed and my game crashed again, and again, and again. At this point I am really frustrated, so I watched some YouTube videos on "how to stop Minecraft world from crashing" and I watched at least 6 and tried everything the videos said and still nothing. And I am really upset because I just wasted pretty much $20 and I wish I could get that money back.
