I'm pretty sure Nanomad just did. Extract all of the files into the root of the directory. So you will have a ML folder, the Canon image folders (DCIM), autoexec.bin, and the .fir for your model or for all of them. You will have to do this using a card reader. If this does not work then you may be having issues with your card reader.
Then go through the Firmware Update process follow the directions from there.
Future assistance many come quicker if you clearly state the issues you are having. 'that doesn't work' doesn't really explain anything and 'what am I doing wrong?' doesn't help other users no what you issue is just by reading the title. How does it not work? Does it fail because the card is 'write protected' or do you have some error? You have to be specific. Also you stated yourself that you had 'fairly high intelligence' but also had problems 'understanding simple instructions.' Read the entire install instructions again all the way through, then try again reading along as you install.
