Game crashes because of addon

[Petar]

I used ODOL Explorer to make save the model T72 as MLOD and used O2 to change the path the star texture to FIA so i simply changed the path from data\east_01.pac to data\guer_01.pac then i made the config.Here it is:

// some basic defines
#define TEast 0
#define TWest 1
#define TGuerrila 2
#define TCivilian 3
#define TSideUnknown 4
#define TEnemy 5
#define TFriendly 6
#define TLogic 7

#define true 1
#define false 0

// type scope
#define private 0
#define protected 1
#define public 2

class CfgPatches
{
     class petREST72
     {
         units[] = {petREST72};
         weapons[] = {};
         requiredVersion = 1.01;
     };
};

class CfgVehicles
{
	class All {};
	class AllVehicles: All {};
	class Land: AllVehicles {};
	class LandVehicle: Land {};
	class Tank: LandVehicle {};
	class T72: tank {};

	class petREST72: T72
	{
	moder="\ResistanceT72\ResT72";
	side=2;
	crew="SoldierGCrew";
	displayname="T72 (Resistance)";
	};
};

However i start Ofp,then place that tank in the editor and hit preview the game crashes.Why is that happening ?
