I log into fantastico's xcontrollers admin and this is the error message i get.

No language files are defined or available.

It appears I have access to all other options ( but have not tested)

where and how do I find and install these language files?

I would run though the install script again and that should fix the problem as well as make sure you have the latest version. At the top of this forum there is a sticky regarding how to install fantastico which can guide you though the process.
