can anyone finds why arduino older code is not working with newer arduino version?
... program works in arduino but won`t get connections with sensors...

Code:

#include <SPI.h>
#include <Ethernet.h>
#include <dht11.h>
#include <SD.h>

dht11 DHT11;

#define nSensores 3
int puertos[nSensores];
float fHumedades[nSensores];
float fTemperaturas[nSensores];

int nFilas=0;
int nFiles=0;

File file;

int iNVisitas=0;

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xEE, 0xEE };
byte ip[] = { 192,168,1, 177 };

// Initialize the Ethernet server library
// with the IP address and port you want to use
// (port 80 is default for HTTP):
EthernetServer server(666);
void setup()
{
  // start the Ethernet connection and the server:
  Ethernet.begin(mac, ip);
  server.begin();

  Serial.begin(115200);
int puertos[]={2,3,4};


   pinMode(10, OUTPUT);
  if (!SD.begin(4))
  {
   Serial.println("Error inicializando SD");
   nFiles=-1;
  }
  else
  {
   nFiles=0;
   Serial.println("SD initializada.");
  }

}

void getdata(int iIndice)
{
  int chk = DHT11.read(puertos[iIndice]);
  fHumedades[iIndice]=-1;
  fTemperaturas[iIndice]=-1;

  Serial.print("Sensor ");
  Serial.print(iIndice);
  Serial.print(" ");
  switch (chk)
  {
   case 0:
   fHumedades[iIndice]=(float)DHT11.humidity;
   Serial.print(fHumedades[iIndice], 2);
   Serial.print(" % ");
   fTemperaturas[iIndice]=(float)DHT11.temperature;
   Serial.print(fTemperaturas[iIndice], 2);
   Serial.println(" o C");
   break;
   case -1: Serial.println(" Checksum error"); break;
   case -2: Serial.println(" Time out error"); break;

  }

   // send a standard http response header
   client.println("HTTP/1.1 200 OK");

   client.println();
   // output the value of each analog input pin
   for(int i=0;i<nSensores;i++){
// for (int analogChannel = 0; analogChannel < 6; analogChannel++) {
   client.print("sensor ");
   client.print(i);
   client.print(": ");

   else
