Unhandled exception at 0x02D5C748

I`m getting exception during debugging:

Exception thrown at 0x02D5C748 in LoongDB.exe: 0xC0000005: Access violation executing location 0x02D5C748.

Also error points to

02D5C748 mov ecx,dword ptr ds:[7A3C60h]
in disassebly window.

I`m trying to compile old game server.

// main.cpp

INT APIENTRY _tWinMain(HINSTANCE hInst, HINSTANCE, LPTSTR, INT)
{
    // ЅыЦ№ЖБД»±Ј»¤ј°µзФґ№ЬАн
    ::SystemParametersInfo(SPI_SETLOWPOWERTIMEOUT, 0, NULL, 0);
    ::SystemParametersInfo(SPI_SETPOWEROFFTIMEOUT, 0, NULL, 0);
    ::SystemParametersInfo(SPI_SETSCREENSAVETIMEOUT, 0, NULL, 0);

    vEngine::InitNetwork();
    vEngine::InitEngine();

#ifdef _DEBUG
    EXCEPTION_PROTECT;
#endif

    CLoong *pLoong = new CLoong;
    if(!pLoong->Init(hInst))
    {
        //іхКј»ЇК§°Ь
        SAFE_DEL(pLoong);
        ERR(_T("Loong init failed!"));
        return FALSE;
    }

    pLoong->MainLoop();

    SAFE_DEL(pLoong);

    vEngine::DestroyEngine();
    vEngine::DestroyNetwork();
    return 0;
}



// Loong.h (contains CLoong)

CLoong::CLoong()
{
    m_bTerminate            = FALSE;
    m_bGameServerLogout     = FALSE;
    m_bGameServerConnect    = FALSE;
    m_pDB                   = new CLoongDB;
    m_dwLogTime             = 0;
    m_szLogFilePostfix[0]   = '\0';


    ZeroMemory(m_szWorldName, sizeof(m_szWorldName));
    //ZeroMemory(m_szServerName, sizeof(m_szServerName));


    m_pLoadSimRole = new tagNDBS_LoadSimRole;   
    m_pCreateRole = new tagNDBS_CreateRole;     
    m_pLoadBaiBao = new tagNDBS_LoadBaiBao;     

    m_pLoadBaiBaoLog = (tagNDBS_LoadBaiBaoLog*)m_pBuffer;   


    m_pLoadRole = (tagNDBS_LoadRole *)m_pBuffer;


    m_Status.dwVerLoongDB       = LOONGDB_BUILD_REVISION;
    m_Status.dwVerBeton         = BETON_BUILD_REVISION;
    m_Status.dwVerVEngine       = VENGINE_BUILD_REVISION;
    m_Status.dwVerServerDefine  = SERVERDEFINE_BUILD_REVISION;
    m_Status.dwVerXML           = XMLREADER_BUILD_REVISION;


    m_MsgCmdMgr.Init();
}

So i found that error appears at

if(!pLoong->Init(hInst))

so seems like something wrong with

pLoong->Init(hInst)

Can someone please provide a solution or some sort of tips that will help me solve this?

Can add any code you need.
