le Lightbox and the slider does not work

hello I bought that plugin, but the Lightbox does not work. I want to slide my picture with the slideshow and all other add on of that plugin but when I click on a picture to see all the picture slide, it does not work. When I click in one picture, it opens the link of the picture in an other page. So everybody can save the picture even with the right click protection add on.

1. when I active the lighbox, I can’t and even the slideshow add on is activate, I can’t see my pictures slide. It does not work. usually when you click on a picture, it opens the slideshow and my pictures slide. But now it does not work and I did not touch anything.

please tell me what’s wrong ??
