My dll´s aren´t being injected more..why not?

Hello guys,i make hacks for Priston tale since 2008,but i stop doing it 2010,and returned again,i found the game packed withthemida,but i got help and found a way to take the adresses,first challenge winned OK.
i had choose to make a simple hack this time,because i was out for a long time and forgot lot of things.
And i removed the code for other functions and i let only hp,mp,res hacks. no my source code(C++).
updated the adresses used in these functions and ok(im absolut certain that my adress are correct).
my dlls aren´t being more injected,i used MESSAGEBOX to notify that its being inject and it don´t works,i used Beep after
while(1) to notify me that it is being injected and also don´t work.
But at 2008-2010 these methods were working (beep and msgBox).
I use those (CreateThread)codes:

Code:

---

BOOL APIENTRY DllMain( HMODULE hModule,
                      DWORD  ul_reason_for_call,
                      LPVOID lpReserved
                                        )
{
        if( ul_reason_for_call == DLL_PROCESS_ATTACH )
        {       
                hThread1 = _beginthread( MainHack, 0, NULL );
                MessageBox( NULL, "DLL INJECTED", MB_OK );
        }
      if(( ul_reason_for_call == DLL_PROCESS_DETACH: )
      {
      }

    return TRUE;
}


int WINAPI DllMain(HINSTANCE hInstance,DWORD reason,LPVOID lpReserved)
{
  switch(reason)
  {
  case DLL_PROCESS_ATTACH:
          _beginthread( KeyCatcherThread, 0, NULL );
//            MessageBox (0, TEXT("Dll Injetada com sucesso!\n"), TEXT("PtCheat"), MB_ICONINFORMATION);
          break;
  case DLL_PROCESS_DETACH:
          break;
  }
  return true;
}

I Tried LoadLibraryA don´t worked too..

What can i do to make my dll injected on process?
When i use Perx injector it says dll injected,but i know its not injected,because i use beep and msg box,and a tool to see if my dll is attachd at game.exe Threads.
When i use Omega injector my pc is restarted..
When i use g3ntool it crash.
Please help me..
Thank you Very Much
