Hello fellow EOS users i have had a 5d mark iii for sometime now, and I finally have all the necessities to use the magic lantern rare recoding function. I have downloaded the recommended firmware, and followed the guidelines of the EOSHD_G3_RAW Guide. I have downgraded the firmware to 1.1.3, formatted my cards with the exFAT file system, installed the magic lantern alpha, and then installed the magic lantern night build, as well as the mac-boot to prepare the cards to make them bootable. After all this was said and done and after I hit update firmware, My camera screen said, Firmware update program. Update file cannot be found, please check the memory card and reload the battery and try again. I am using a 64 GB compact flash UDMA 7 LEXAR Professional 1000x CF card, and a PNY Professional X 64GB class 10 SD card. Can anyone give me some insight to what I might be doing wrong?!!!!!!
