After updating the hitMag theme, the slider is not working properly

Before updating the theme, everything works perfectly. But after updating the hitMag theme, the slider is not working properly. It shows the post but it show all the post line by line instead of sliding. Normally I am expecting that it should be showing one post into the slide and then after some second, another post will appears by sliding. But after updating, It just shows all the post line by line and the sliding doesn’t work. So what’s the problem?
