If that does not work, try deleting and then re-installing your app.
First, make sure you're using iOS version 4.3.3 or later so you can access the "Not On This iPhone/iPad" section of the App Store. On an iPhone, you can find this section in the App Store > Updates > Purchased > "Not On This iPhone." On an iPad, you can find it under App Store > Purchased > "Not On This iPad."
Once you've made sure you have access to this section of the App Store, please deleteThe Simpsons: Tapped Out from your device. To delete the app, tap and hold the "Tapped Out" icon on the home screen of your iOS device until you see an "X" in the upper left-hand corner of the icon. You will get a message asking if you want to "Delete Tapped Out." Tap the "Delete" button to remove the app.
Once the app is deleted, go to the Purchased -> "Not On This iPhone/iPad" section of the App Store and find "The Simpsons: Tapped Out." Tap the "Install" button to reinstall the app.
