See if the Base Files have been downloaded completely. Uninstall the app, delete the folder Aura and reinstall. Then use the Sygic Downloader to download the files again. You can also download the Base Files and Maps provided by me(check the Opening Post for the link) if you can't access WiFi, or for any other reason you don't want/can't download everything again using your phone's data connection. Hope it works for you this time around! Do keep us posted.
