Burning bootloader to Mega2560

Hello!,

I think i got my bootloader broken becouse i can't upload new code.. The code on the Arduino is still working though.

I have a AVR Atmel witch should burn the code from the com1 to the arduino but it doesn't work. I get this error:
avrdude: stk500_program_enable(): no device
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

I also tried the parralel programmer but that doens't work ether, i get this error message:

avrdude: can't open device "giveio"
avrdude: failed to open parallel port "lpt1"

I can't find what i am doing wrong now. i followed all the instructions on the Arduino website.

Thanks in advance,

Jan
