I just downloaded your app and it won't run.

This is a common problem for all apps you might download from the App Store. Try the following steps. 

1. Restart your device by completely turning it off, and back on. Try load the app again. If it still won't load, see step 2. 

2. Re-download the app: If downloading via the device on the App Store, ensure that you have deleted the app from your device before re-downloading. If downloading via iTunes, be sure to delete the app from your Applications folder, before redownloading, and syncing to your device.
