slideshow giving error

I’ve installed the latest version of NextGEN gallery (version 2.0.40). All other options like Basic Thumbnails, Basic ImageBrowser, Basic SinglePic are working fine but when I tried to create a Basic Slideshow then it’s not working! I can only see the slideshow loading icon but no slideshow images. I’ve check the error console & it shows following error:

TypeError: jQuery(...).nggShowSlideshow is not a function

timeout: 10000      });

Any help to resolve this? thanks!
