What happened?

The previous version of this app was golden. I used it every day to study anatomy for my class, even though I unintentionally paid $60 for it (clumsy clicking). Ever since the new update came out I’ve been viewing nothing but a glitched screen that doesn’t show me anything beyond the main menu. I’m on the verge of deleting this app. Please fix it.
