Arter IOS9

Ive already purchased LDOCE5 before. I was using it on iPhone and iPad properly. After I upgrade my iPad to ios9, LDOCE5 no longer works on iPad. I decided to wipe it away on my iPad and than to download it again in order to refresh it, so I would be able to use it again properly. But unfortunately I didnt succeed in working LDOCE5. Ive just purchased this new one, but this is also not working on my iPad. Is it fair? I have paid for the same dictionary twice! Is it fair!??
