Megamenu not working in responsive

We have just integrated JUXmegamenu in our site. It's working fine in big screen but in responsive drop-down is not working.

Hi Jorg Bergner,
Thanks you for using our product.
Please try to this solution. Go to the advanced tab and enable ( if you're off it) or turn off ( if you're turning it) Because can your site has or hasn't load Jquery / can conflict jquery.
If it doesn't works. Please give me link your site and your account of administrator via mail: This email address is being protected from spambots. You need JavaScript enabled to view it.
I will check it for you soon
