Moved from another thread and edited. A lot of questions about hex 10uc.

A couple of days ago I installed an app in my tablet called Deepware Changes, which I am finding quite useful. My book is a cheap Spanish version that comprises the hexagram meaning, a Confucius quote and a passage of Tao that suits that hexagram. The book is not bad but not too good either, so here are my questions:Asking about my mum's health, who is facing bodily depression, I got hexagram 10 unchanging. The lines I got were 7 7 8 7 7 7 from bottom upwards, using the app, mind you. But my book indicates the lines 9 9 6 9 9 9. Is it the same in other books? And why the book doesn't contemplate my lines? What can you tell me of an 10uc?How many times a day can you consult the I Ching, whether I ask about different things, or if I ask about the same situation? How often do you use it?Considering the separate trigrams, what insight I am supposed to get by reading their meaning? Or better only consider the Hexagram fully?Sorry about so many questions. My interest in I Ching come from long but I had it abandoned and I just started using it again...
