Classes Will Not Load

This app used to be great. It was a way to easily access stuff from my classes without going to the website and logging on. But for the past week it just has a buffering wheel where my classes should be, and my classes never load! I have tried restarting my device and the app and my classes still wont load! I also tried logging out and then logging back in, but when I hit "continue" to log in, it gives me another buffering wheel.
