So I got my brand new 5D about a week and a half ago (2.08 version) and tonight I went and downloaded the newest ML version 0.1.9 created for the newer 5D's at this LINK:Support for 5D Mark II with 2.0.8 - Magic Lantern firmware development | Google Groups (http://groups.google.com/group/ml-devel/browse_thread/thread/9ab24a6168d3f14e)

After extracting the files I transfered them to my CF card then inserted the card back into the camera and turned the camera on. I then scrolled to the update Firmware option and clicked "OK".

For about a half a second the screen read "loading" then went black. I waited about a minute then pressed the Liveview button, but still nothing. I then clicked the other buttons but nothing worked. So I turned the camera off then back on and the LCD read ERR.

Once I removed the battery then put it back in the camera worked fine but without Magin Lantern.

BTW, I am using the Transcend UDMA 600x 32GB CF card

Can somebody tell me what I'm doing wrong please? Got a major shoot soon;)

Thanks much!
