I bought the full version, but the additional levels won't open. What should I do?

You can re-download the app for free. Please follow these steps: delete the app, restart the device, download the app again, click 'Buy the full version' in the app. Please make sure you are using the same iTunes account as before. The market will recognise that you have already paid for the application. If that doesn't work, please fill in the support form below and we'll get back to you.
