Burning Boot Loader with BitBang

I am trying to burn a boot loader to my seeeduino with the bit bang method found on the Burning the Bootloader without external AVR-Writer page.

when I try to do anything with the avrdude GUI, I get the error:
avrdude.exe: ft0 open failed

The seeeduino is connected to the computer and shows as COM4, but avrdude is not communicating with it.

Any ideas?
thanks
