I'm not much of any help, but you should probably see if the game you're trying to play has all of the, I guess you could say, "neccessaries". Such as, if they game needs lots of space or a certain program to run, you should probably double-check that you have them. I'm not too sure what czero is though(to be blunt). So I'm not much of help, but I hope you get your game working soon! :]
