Problem with re-uploading ATmega8U2 firmware

I damaged my Arduino bootloaders some time ago (328P+8U2), so I bought AVR Pocket Programmer from sparkfun.
It looks like I uploaded Arduino Optiboot Bootloader into 328P successfully, but I cant upload firmware into 8U2.
I connected another one ICSP header on my Arduino Uno and I tried to upload ATmega8U2 firmware Arduino-usbserial-uno.hex from Arduino-0022/hardware/arduino/firmwares/arduino-usbserial directory using avrdude 5.10, but this this appeared: http://img703.imageshack.us/img703/1102/avrdude.jpg

Can somebody help me, please?
