Common gotcha with the jquery ui module is failing to add the symbolic link within the module directory to the jquery ui library itself. If you download the full jquery ui bundle to sites/all/libraries, you need to do this:

cd /path/to/sites/all/modules/jquery_ui
ln -s ../../libraries/jquery_ui/development-bundle jquery.ui

I suspect this is your problem!
