Arduino mega with fingerprint sensor Serial error

hi friend…
i have create coding for fingerprint with arduino mega and use hardware serial.
this coding already create last year and all work fine.
but after i try use this coding for same project during compile or verify it error with
no matching function for call to `Adafruit_fingerprint::Adafruit_fingerprint(HardwareSerial*)

can anyone help check my coding?..thanks…

#include <Adafruit_Fingerprint.h>
//#include <SoftwareSerial.h>

uint8_t id;

uint8_t getFingerprintEnroll();

// Software serial for when you dont have a hardware serial port
// pin #2 is IN from sensor (GREEN wire)
// pin #3 is OUT from arduino  (WHITE wire)
// On Leonardo/Micro/Yun, use pins 8 & 9. On Mega, just grab a hardware serialport 
 //SoftwareSerial mySerial(19, 18); // use for UNO
//Adafruit_Fingerprint finger = Adafruit_Fingerprint(&mySerial); // use for UNO

// On Leonardo/Micro or others with hardware serial, use those! #0 is green wire, #1 is white
  Adafruit_Fingerprint finger = Adafruit_Fingerprint(&Serial1); // #19 is green wire, #18 is white on MEGA
// serial1 for mega pin 19,18 pls check MEGA spec

Unfortunately the current version of Adafruit_Fingerprint doesn't support the use of HardwareSerial, it only works with that horrible SoftwareSerial. You might change that by replacing every occurrence of SoftwareSerial by HardwareSerial in the library files.

ooo..ok2 thanks friends..
