If so, it could mean that it had a problem loading the text for your language.
To fix this, open the app and:
1. Tap the silver Gear icon to go to Settings
2. Tap the last of the four tabs in the Settings screen - this tab is called Help but it may not show a title.
3. On the left hand side, tap half way down, where it says "Advanced" in the screen shot below.
4. Finally tap the "Reset Language" button.
After a moment, the app will re-display the text in your language.
If you continue to have problems, don't hesitate to contact us.
