How do I solve, “‘iBank 5’ is damaged and can’t be opened.”

This message seems to appear for some customers who have bought iBank 5 from the Mac App Store. It is happening because Apple has an expired certificate. It isn’t an issue with IGG. The full message reads:

“iBank 5” is damaged and can’t be opened. Delete “iBank 5” and download it again from the App Store.

Open the Applications folder and drag the existing iBank application file to the Trash.
Next, open App Store and click ‘Purchased’ from the top of the App Store window. From the list of purchased apps, you should see iBank and an ‘Install’ button.  Click ‘Install’ to reinstall the iBank application file.  This should resolve your issues.

DO NOT DELETE YOUR iBank DOCUMENTS! If you delete your documents you will be deleting your data. If you delete the application, all of your data will be left untouched.
