Image slider does not work anymore

Hello, I hope someone can help me with fixing the image slider. It did work before I installed the qtranslate plugin, but soon enough I realized that this plugin does not work with the Image slider.Therefore I uninstalled qTranslate again. Everything seems fine, but then i noticed that the image slider does not advance to the next picture anymore. The settings I had before are still the same. Can't figure out what to do anymore. I tried reinstall the Catch Everest Pro theme again, but that did not help again eighter. Could someone please help me? I'm fairly new to webdesign. Thanks in advance, Bob
