I still can't install the update but I'm not sure whether I really want it or not. According do Ubi's forum you should ony install it if you encounter certain Problems solving a Puzzle in Spire. Otherwise don't install it caus it can chash the game... i read that some people installed it, solved the puzzle and then downgraded again to play on... what a crap is that?
I really like the game but the support policy makes me really mad.
