Event calendar 1.2 problem with language [SOLVED]

[Amigamerlin]

Hello, just update Event calendar to release 1.2 from 1.1 and in the Administration  backend no words are visible.
If I switch the language to english or greek no problem at all but if I use Italian language no more language file.
Then I copied the english.com_eventcalendar.php into italian.com_eventcalendar.php to have the english interface even if I use Italian admin language but the language still not visible.
Anyone can help How to fix it?
Thank you.

Problem solved,
The language file must be copied in /administration/language/italian/italian.com_eventcalendar.php 
Thanks to Andrej Kambalov and Apostolos Koutsoulelos for the head's up.
