[arthurfilmmaker]

I formatted the sd card inside the camera.
ran the bootflagfir in the cam.
put the SD card back in the pc. deleted the bootflag file.
put on the SD card the ML folder and the autoexe.
i ran the eosCard to make in bootable - i checked the EOS_DEVELOPE & BOOTDISK (doesn't say successfull.. it says  -
 Drive 1  Ready Fat VBR Loaded )

I'm running on Win 7  64bit.

Please Help..
