Problem with layerslider

Hello,

I just bought the theme and layerslider isn’t working for me. I can create a new slider but if I try to add a new layer it won’t save. When I click on the tabs in ‘slider settings’ nothing happens, like if there wouldn’t be a button at all. I installed the layerslider version, which you guys were posting on other topics. Really don’t want to miss out on this plugin.

Thank you advance for any help.
