Trying to make a lua executor, but crashes as soon as executes.

[MGPie]

Hi, I'm trying to make a lua executor but it seems to crash as soon as i try to run anything.

enum LuaInterfaceType
{
	LUAINTERFACE_CLIENT = 0,
	LUAINTERFACE_SERVER = 1,
	LUAINTERFACE_MENU = 2
};

class CLuaShared
{
public:
	virtual void            padding00() = 0;
	virtual void* padding01() = 0;
	virtual void* padding02() = 0;
	virtual void* padding03() = 0;
	virtual void* padding04() = 0;
	virtual void* padding05() = 0;
	virtual DWORD			GetLuaInterface(LuaInterfaceType type) = 0;
};

typedef void* (*CreateInterfaceFn)(const char* Name, int* ReturnCode);

// Lua function prototypes.
typedef int(__cdecl* _luaL_loadstring)(void* state, const char* s);
_luaL_loadstring  lua_ls = NULL;

typedef int(__cdecl* _lua_pcall)(void* state, int nargs, int nresults, int errfunc);
_lua_pcall lua_pcall = NULL;

void ExecuteLua(string code) {
	HMODULE luaShared = GetModuleHandleA("lua_shared.dll");
	if (!luaShared) return console.AddLog("[error] Could not get lua_shared.dll");
	CreateInterfaceFn CreateInterface = (CreateInterfaceFn)GetProcAddress(luaShared, "CreateInterface");
	if (!CreateInterface) return console.AddLog("[error] Could not get CreateInterface from lua_shared.dll");
	CLuaShared* ILuaShared = (CLuaShared*)CreateInterface("LUASHARED003", NULL);
	if (!ILuaShared) return console.AddLog("[error] Could not get LUASHARED003 from CLuaShared");
	DWORD CLuaInterface = ILuaShared->GetLuaInterface(LUAINTERFACE_CLIENT);
	if (!CLuaInterface) return console.AddLog("[error] Could not get LUAINTERFACE_CLIENT from CLuaInterface");
	DWORD pGLuaState = *(DWORD*)(CLuaInterface + 0x4);
	if (!pGLuaState) return console.AddLog("[error] Could not get pGLuaState from CLuaInterface");
	lua_pcall = (_lua_pcall)GetProcAddress(luaShared, "lua_pcall");
	if (!lua_pcall) return console.AddLog("[error] Could not get lua_pcall from lua_shared.dll");
	lua_ls = (_luaL_loadstring)GetProcAddress(luaShared, "luaL_loadstring");
	if (!lua_ls) return console.AddLog("[error] Could not get lua_ls from lua_shared.dll");
	lua_ls((void*)pGLuaState, code.c_str());
	lua_pcall((void*)pGLuaState, 0, 0, 0);
}

now whenever i try to execute anything via ExecuteLua and a console window if I do a simple print('1') it does it, but if I try again it crashes and anything longer crashes aswell. Does anyone know why?
