Why is my new app code invalid or saying it has already been used?

Make sure you have downloaded the City Saver app for the correct city and that you have the correct year (ie. 2018) of the app for the City Saver book you have purchased. Please note, the code printed in your book is NOT your app code; it is your book code. Please visit the app activation webpage for your city to activate and receive your app code.
