Missing slideshow

I had created my first slideshow with this plug-in early last week (and was very happy with it). Our site was migrated to another server mid-week and ever since the contents of that slideshow are gone. My IT guy suggested I contact you to see if you had any suggestions as he can’t see that it’s anything on his end b/c everything else on WP transferred with no problem. Any ideas??
