It appears your device doesn't support v.0.2.1. Please download the rebuild version available in demo. It works on most devices. Right now it doesn't have much content but will be adding more in future.
The reason of rebuilding is because the old v.0.2.1 doesn't work with all devices but the the new rebuild does. I have to make maps from small chunks that's why it is taking longer than expected. Sorry for inconvenience.
