italian translation

Hi Pl

I'm using JEvents (_GREAT_) for an italian site.
as the default installation is missing the italian file I've translated en-GB.com_jevents.ini in italian
and named it
it-IT.com_jevents.ini

copied it in the Language directory... nothing changed at all

I confess. I translated, but I've not read a word of manuals and Hot-To-Do... (sick).
Sorry I'm lacking time like deserts lack water lakes...

Any help or info (or url ) ?
Thanks
