hi!
I have the same problem here, under linux, ufo:ai version 2.1. these screenshots describe precisely what I get...
my system's default language is spanish. i've tried copying and pasting the english ufoai.mo to both /base/i18n/es and es_ES, no result.
I can't start the game with "LANG=<whatever>; ./ufo", the answer is always "there's no such file or directory " (I don't really know how to input this; I've tried with and without quote marks and brackets, no result)
but, in fact, "./ufo" does not start the game in my computer
LANG=en; ufoai starts the game, but doesn't change anything.
any help?
thanks!
edit: I have reinstalled, also tried "ufoai +set s_language en_US", "ufoai +set s_language en", the answer is always the same:
...could not set to language: <whatever>
maybe somehow I don't have the language packs properly installed, even if the ufoai.mo files exist?
the tutorials seem to work alright, always in english
