Cannot install

Hello.

I followed the installation instruction. I placed the module as it was unpacked in an html_area folder in the modules drupal folder, and then unpacked the xihna into /drupal/html_area/xihna .

Despite that, I still get " Xinha/HTMLArea is not installed, download Xinha from http://xinha.python-hosting.com/wiki/DownloadsPage (recommended), and install it into the htmlarea module directory. "

Also, the htmlarea js is not called in the header. Also you can see other js scripts I am using
