One of my favourite games, but it keeps crashing

I just downloaded this game again, and I love it, its in my top 5 favourite games, but it keeps crashing. Every time I end a level, it crashes and I have to load up the game again. But when I got to the point when you get the plant that takes out tomb stones, it crashes, and it wont open up the game entirely now. Someone should really fix this bug, because Im getting more annoyed every time I want to play it, but I am unable to.
