I have this app on my iPod and when i open it only goes to the main menu what do i do it only happens on this one app
Try uninstalling by holding your finger on an icon in the main menu until it starts shaking then tap the X that appears on it and reinstalling the application. Re-sync the application from iTunes or download it directly from the application store.
You might have to erase it and get it again..or update it ..both good luck
Delete it then download it again.
