Can't save – Tomb Raider II Review

The Great Wall was good but when I got to the next level i saved it. It was getting late and I wanted to play the next day. when I woke up and started playing it won't let me play it. And my screen goes black all the time. I though was my iPad but I started that over 3 times and it still not working what should I do please!
