KEEPS CRASHING! PLEASE FIX!!

I bought this app, as my teacher recommended. We use this exact program in class (same guy and everything). I really think it will help with my finals. However, it has crashed 4 times within 10 minutes!!! PLEASE FIX THAT!! How can I study if it keeps crashing?! Other then that, great!!
