Very strange behavior after compiling for PC

I am compiling my project for PC

When i am in the unity editor the game is running fine.

i have a static class in which i store my game parameters

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 public static class game_params
 {
 public static List<Enviroment> enviroments;
 .....

and in my main script i create one cube and i access the game_params class and the reference to that class is causing the problem because if i remove it the cube is created (this is happening only after compilation)

and the only line of code after the crationf of the cube is game_params.enviroments = new List();

in the game the console tells me : "an exception was thrown by the type initializer of game_params"

how do i fix that ? i guess that fore some kind of reason the exe does not compile this class but what can i do about it :? or is there a problem because it is static i cant even add the game_params class to an empty game object, it says: "can't add script behaviour game_params. The script class can't be abstract."

or am i missing some reference or something i dont know i have no clue... i dont have namespaces too
