Hi

I have installed the contact importer module,

After i installed the lightbox2 module,

Then i looked into the site configuration/contact importer,

It asked ,Select the Retrieval engines:Octazen

then i selected and submitted , then it throughs the error like

* Octazen requires one or more library files provided by the retrieval service.
