Rayman Jungle Run crashes

[Darialan]

Now normally, if an app just crashes each time, I just delete it and redownload it. I did this initially to see if it'd give back my save that I lost. I figured icloud would've kept my save and I'd get it back. Well, I redownloaded it, it started showing all these jewels even in places I haven't beat, then it crashed. And now Every time I delete and run, it crashes. Can someone help me? Thanks.
