I'm sorry to steal this thread, but there is no *.cfg-file anywhere in my UFO AI folders. I've tried uninstalling and reinstalling, but to no avail.
*edit*
When I try "s_language en" in the console I only get;
...could not set to language: en
...could not set to system language
My guess is it's because there's no config-file to write to?
*edit 2*
My troubles seem to be over for the time being. I just installed the 2.1(.1) beta over the old 2.1 installation and now it works.
There's still no config-file, though. Hmm. :?
