problem with config oscillator on pic18f25k80

Hi, I'm tryng to use the PIC18f25k80 with the internal oscillator (HF-INTOSC 16MHz) and the PLL enabled for work at 64MHz.
this is my code:

Code:

#include <18F25K80.h>

#FUSES NOWDT //No Watch Dog Timer
#FUSES WDT128 //Watch Dog Timer uses 1:128 Postscale
#FUSES VREGSLEEP
#FUSES INTRC_HP
//#FUSES SOSC_HIGH
#FUSES NOXINST //Extended set extension and Indexed Addressing mode disabled (Legacy mode)
#FUSES INTRC_IO //Internal RC Osc, no CLKOUT
#FUSES PLLEN
#FUSES FCMEN //Fail-safe clock monitor enabled
#FUSES NOIESO //Internal External Switch Over mode disabled
#FUSES NOPUT //No Power Up Timer
#FUSES NOBROWNOUT //No brownout reset
#FUSES BORV18
#FUSES ZPBORM
#FUSES WDT_NOSLEEP
#FUSES WDT1048576
#FUSES MSSPMSK7
#FUSES NOMCLR //Master Clear pin used for I/O
#FUSES STVREN //Stack full/underflow will cause reset
#FUSES BBSIZ2K //2K words Boot Block size
#FUSES NODEBUG //No Debug mode for ICD
#FUSES NOPROTECT //Code not protected from reading
#FUSES NOCPB //No Boot Block code protection
#FUSES NOCPD //No EE protection
#FUSES NOWRT //Program memory not write protected
#FUSES NOWRTC //configuration not registers write protected
#FUSES NOWRTB //Boot block not write protected
#FUSES NOWRTD //Data EEPROM not write protected
#FUSES NOEBTR //Memory not protected from table reads
//#FUSES NOPMPEMB //PMP Pins are not on the external memory bus
#use delay (clock=64M)

when I compile I get an error on the #use delay(). The error says:"Option invalid Internal oscillator frequency wrong.

Anybody can help me?
Thank you for the reply

You have multiple oscillator fuses. You should only have one.

You also have multiple Watchdog fuses.

Here is a recent thread on oscillator setup problems with the "K80" family
of PICs. This thread may, or may not help:
http://www.ccsinfo.com/forum/viewtopic.php?t=45164

If you need more help, post your compiler version. We don't remember
your version from previous threads.
