Problems with clickbank plugin/widget

I am having problems with the clickbank plugin. I have installed it and that went well, although when I go to make it a widget I can not see it on the widgets page. How is that even possible? Please if anyone can help, do. I really would appreciate it. I have installed it and unistalled it just to reinstall it again. Hoping to see a change, and be able see it in the widgets. Nothing im doing seems to be working.
