To everyone who is getting the "This version has expired" message just follow the steps below. There is no need to have any Xposed module installed.
1. Force stop the app.
2. Set the phone date to September 27, 2014
3. Open the Here maps app. It should not show the error now.
4. Exit the app and set the phone date back to the current date.
The app should still be working now
**updated: app does not works when I changed the date on my phone.
