Slider broken

I launched a site Friday and it was great.   We had a server issue on Saturday and the site went down, when it came back up the home page slider was broken.    I've rebuilt it and checked all the settings but can't get it to work. Anyone experience this or have a tip to get it working again?     Is there a specific file I should edit or look for a code? http://www.ironhorsemechanical.net
