It worked for a bit...

I downloaded this app, and it worked perfectly for the first 15 minutes, then it signed me out suddenly, and when I got log in, it crashed. I tried reopening it, now its crashing on launch every time. Please fix this.

- This problem occurred on my iPod touch 5th generation (newest model, iOS 8.3)
