Right Sidebar Disappeared / Atahualpa Theme

I added an image to my right sidebar using “Simple Image Link Plugun” (a plugin I have that allows a picture to be linked to a page http://blog-well.com/downloads/wordpress-image-link-plugin/) The plugin was activated on my wp, and in use by other places in the sidebar so I know it worked. When i added a new image, and saved it, the entire right side bar dissapeared and has not returned. It shows in the template itself, but not on the site. What should I do to recover it?
