Troubleshooting Apps
In a perfect world, apps would never misbehave. Unfortunately, it’s not a perfect
world. An app may quit the moment you launch it, or cause your NOOK Tablet to
restart, or do any number of odd things. If that happens, try these steps:
• Launch the app again. There’s no particular reason why relaunch should
work, but it often does. When you launch the app again, it just may work
properly.
• Archive or delete and reinstall . There may have been an oddball installa-
tion problem. So archive or delete the app, and then reinstall it. That action
sometimes fixes the problem. When to archive and when to delete? If it’s a
for-pay app you’ll want to archive rather than delete it, or else you’ll have to
pay for it again.
• Restart the NOOK Tablet.
Just as restarting a computer sometimes fixes
problems for no known reason, restarting the NOOK Tablet may have the
same effect.
If none of this works, then it’s time to uninstall the app. Don’t fret; there are
plenty more where it came from.
