No sliding and doubling up

Since my client updated smooth slider and wordpress it is no longer working.

It is all jumbled (looks like the sliders are maybe sitting on top of each other) and it no longer slides.

Here is a screenshot: http://i1250.photobucket.com/albums/hh540/sommerfugldesign/s_zps416cec63.png

Any ideas on how to fix it?
