Hi everyone im new in Arduino. I have started a new project but i have a trouble with FPS-GT511C3 and Ethernet Shield i cant use tohether them. Could you help me ?

#include <SPI.h>
#include <Ethernet.h>
#include <SoftwareSerial.h>
#include <FPS_GT511C3.h>

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
EthernetServer server(80);
FPS_GT511C3 fps(52, 53);

void setup() {
  Serial.begin(9600);
  Serial.println("Wait for settings");
  delay(1000);
  Ethernet.begin(mac);
  Serial.println("Ethernet has started..");
  delay(1000);
  server.begin();
  Serial.print("Server is started..");
  Serial.println(Ethernet.localIP());
  delay(2000);
  fps.Open();//If i remove this and below code then it works correctly.
  fps.SetLED(true);
  delay(2000);

  Serial.println("Everything is ok");
}

If i remove fps.Open(); project is working correctly.But i put this code i cant see “Everything is ok” text.
