Function can't be called

Yesterday night I got this code working but then I accidentally pressed CTRL + Z on a wrong script and I can't figure out what I destroyed by doing that..

When I'm trying to call a function on another script using:

Client.js

 print("this is printed");
 var player = Player.stringToPlayer("some text"); /*Where Player is the name 
 of the script and stringToPlayer is the name of public static function*/ 

Player.js

 public static function stringToPlayer(playerData:String) : Player{
     print("This is never printed?");
     return new Player(playerData);
 }

So it kind of gets stuck at the point where it calls another function.
