i just downloaded iscore but there are no screens available for game manager, player maneger etc. i am using ipad for baseball. Help

When you first install iScore those screens are just empty lists. You would tap the button to add a new game or team from the list. If you are not seeing an option to add new data then it sounds like maybe iScore did not fully install. Try removing it from your device and downloading again from the App Store.
