Help: 5d Mk ii won't detect firmware off card and won't display live-view

[bigshave]

I keep getting this message, every time I try installing the new firmware.

"Update file cannot be found. Please check the memory card and reload the battery and try again."

I originally had the magic lantern raw module and used another card without ML on it and the camera has been messed every since. There are purple bars and no live-view access.

Here's what it is causing:
