Will someone please help me?

So far I have Image Handler 2 installed. I tried to install AJAX Image Swapper without success so I deleted all associated files, but it still shows up under Configuration (which is annoying).

Fual Slimbox shows up, too with a blank page.

Then, I tried the Lightbox and everything went well until I got to Configuration -> JQLightbox which shows a blank page with Title Value Action.

I need some major help. I would appreciate any help at all!
