Synchronizing old information onto a new device (or a device which has had the app deleted and subsequently installed).
First, make sure that you have the latest configuration installed. You can check the version number in the lower left of the title screen and make sure that it ends with "!001" (or later), as in this image:
Once you have configuration "001" or later loaded, go to the Parent menu by using the slider in the upper left corner of the title page. On the third tab, there will be a new button called "Sync".
Press this button, confirm at the next dialog, and then it will load your archived data onto your device.
