App doesn’t seem to work – iTunes U Review

I have for the past year and a half tried to use the app to give myself a refresher but the app needs to be updated. So when I go to update the app it says I have to buy the app again. I go to the App Store to download and it actually like it is going to download but it never does. The app came preloaded on my phone.
