problem to connect to wi fi

Hi
can anyone please assist me with connecting the ELECROW WIFI SHIELD 1.0 with UNO board.
Im using the file from the website but cannot connect. code is as follows

#include "Wifly.h"
#include <SoftwareSerial.h>
WiflyClass Wifly(2,3);

void setup()
{
  Serial.begin(9600);
  Wifly.init();
  Wifly.setConfig("xxxxxxxxl","xxxxxxxxxxxxx");
  Wifly.join("Supafuel");
  Wifly.checkAssociated();
  while(!Wifly.connect("10:0:0:12","90")); ?? Where do i get this setting from

  Wifly.writeToSocket("Connected!");
}
void loop()
{
  if(Wifly.canReadFromSocket())
  {
    Wifly.readFromSocket();
  }
  if(Serial.available())
  {
    Wifly.print((char)Serial.read());
  }
}

I get a error message from serial monitor as follows:
