Sorry to hear about that. If an app (ours or any) get temperamental there are a couple of things you can do. First is to simply quit the app and reopen it. If that does't work you can try turning your iPad off and on again and if it's still not working, try resetting your iPad. The last measure is to delete and reinstall the app. Here's what I'd recommend in this order...I'm having issues posting on forums with the new update. Used to before the upgrade I could write a book but now I'm lucky to write a few lines to a paragraph before it shuts down and returns the app page.
