PICKIT3 suddenly fails to program & read PIC24fj64ga704 device.

Our system with PIC24fj64ga704 has suddenly failed to program & read data from PICKIT3. We tried with new PCB also but response was same. PICKIT3 is detecting the pic24 device & its voltage. It also  erasing data & blank checking with IPE program  successfully. But we are not successful in programming pic24 device.
PIC18 projects are still being programmed & read with this pickit3.  It will be very helpful, if you could suggest some remedy.
Thanks in advance.

     BWRP = 1, BSS = 3, BSEN = OFF, GWRP OFF, GSS Disabled, CWRP= OFF, CSS = STNDRD, AIVTDIS = OFF, FNOSC = 0, PLLMODE = DISABLED,  IESO = OFF, POSCMD = NONE, OSCIOFCN = 0, SOSCSEL = 0, PLLSS = PLL_FRC, IOL1WAY = OFF, FCKSM = CSDCMD, WDTPS = PS32768, FWPSA = PR128, FWDTEN = OFF, WINDIS = OFF, WDTWIN = WIN25, WDTCMX = WDTCLK, WDTCLK = LPRC, BOREN = OFF, LPCFG = OFF, DNVPEN = ENABLE, 
    ICS = PGD1, JTAGEN = OFF, ALTCMPI = DISABLE, TMRPIN = OFF, SOSCHP = 1, ALTI2C1 = 0,

    Your PICKit3 could have just suddenly died.
    You can try reloading the software by holding the button down while plugging in the USB.
