FAQ: This App does not work properly it keeps on crashing, why?
Sometimes Apps just do not download properly. You will need to download it again, for free, using itunes. See Apple Support Pages
About half way down the page there's a set of instructions that starts 'Reinstall the affected application'. Once iTunes has it then you sync your device and it should then work. If it does not then please to contact me.
