The slider doesn't work on Chrome. I had this issue with Views Nivo Slider 7.x-3.x-dev and also with Views Slideshow 7.x-3.0. It works perfectly on other browsers but in google chrome. To fix this problem, I simply added width and height of the slider to the css file. Even thought we have given those using image style in drupal, you can see there values go to 0px or 1px in chrome. Check for the element where those values are 0 and add styles to override those values in css. hope this would be helpful for now.
