Te dejo los pasos a seguir para instalar el Jquery_ui, que esta claro q no lo hiciste por completo:
-- INSTALLATION --
* Copy the jquery_ui module directory to your sites/all/modules directory, so it
is located in sites/all/modules/jquery_ui/.
* Download the jQuery UI 1.6 release from:
http://code.google.com/p/jquery-ui/downloads/list?q=1.6
* Put the downloaded archive into the directory:
/sites/all/libraries/jquery.ui-1.6.zip
* Extract the archive. This will create the following sub-directory:
/sites/all/libraries/jquery.ui-1.6/
* Rename the sub-directory into "jquery.ui":
/sites/all/libraries/jquery.ui/
so the actual jQuery UI JavaScript files are located in:
/sites/all/libraries/jquery.ui/ui/*.js
* Enable the module at Administer >> Site building >> Modules.
Saludos.
