First off, I would like to thank you guys for putting together this guide. I am having a problem with installing the ML onto my 5Dmark 3. I am running windows. Using the 64gig 1000x komputer card. I have followed the steps in the guide to the tee (1.13 firmware), and when I load the ML on to the card and use EOScard, then try installing the firmware, it just hangs and says it cannot find the firmware. I then I have to take out the battery out to get the camera to function again. I noticed that my card is exFat (image in the guide shows the card is FAT32). Is that the problem? If so, how do I fix that problem?
