BlackMagic _magic = Globals.Magic; 
            if (_magic.IsProcessOpen) 
            { 
                while (true) 
                { 
                    //check the looting window is opened 
                    if (_magic.ReadInt64((uint)0xB71B48) != 0L) 
                    { 
                        uint codeCave = _magic.AllocateMemory(); 
                        try 
                        { 
                            _magic.Asm.Clear(); 
                            _magic.Asm.AddLine("mov ecx, 0"); 
                            //call auto loot 
                            _magic.Asm.AddLine("call " + (uint)0x4C1FA0); 
                            _magic.Asm.AddLine("retn"); 
                            _magic.Asm.InjectAndExecute(codeCave); 
                            _magic.Asm.Clear(); 
                        } 
                        catch (Exception ee) 
                        { 
                            MessageBox.Show(ee.ToString()); 
                        } 
                        _magic.FreeMemory(codeCave); 
                    } 

                    Thread.Sleep(1000); 
                } 
            } 
            else 
            { 
                _magic.OpenProcessAndThread(SProcess.GetProcessFromProcessName("Wow")); 
            } 

Most of the time it worked, sometimes crash，could anyone tell me why ,thx!
