Two problems during lauching phase

Hi there,
I'm french so I hope you'll excuse me if I make some mistakes in my sentences. I discovered X mage recently because I was searching a programm more realistic for Magic. Cockatrice and MWS are good but ugly and it's easy for somoen to cheat because there is no automatization of the game.
So I installed the last version of the programm but two problems occured.
First, the launcher doesn't want to download all of the card, there is approximatively 900 cards which are missing.
Then I doesn't understand how to play with the AI. When I try to launch the game, it crash. How do I play with the computer step by step please ?
Oh and one more thing, there is several pre-construct deck, so I tried to play with the 7th edition (white) and the programm told me that the card are not there and I can't play. But why does the programm propose to play with a deck if this deck doesn't exist ?
Thank you for reading this, I hope you will answer and thank again !
