Help to load firmware

I had a problem that the usb to the controler broke off. i now have a replacerment and have downloaded the firmware from vigo.
Could someone tell me how I should start as I have no idea of programming. I have tried but failed.

What firmware are you referring to? What controller?

Standard vigo controller, i have the firmware loaded with xloader but still problems with avrdude and avrdude.conf
Also libusb0.dll
Thanks for replying and hope you can point me in the right direction.
I get problems loading the above fils with Xloader saying COM3 cant open, I have added seval other numbers but no joy.
