Actually, okay, I think I've figured it out. It's very strange, for some reason I can't get Magic Lantern using the standard steps in the instructions and all the installation tutorials.
What works for me, is I put the installation firmware, autoexec.bin, etc. on my SD card. I prepare it, and the only way to get Magic Lantern working is by installing the firmware and then switching over to movie mode. Unfortunately, when I try to reboot my camera, I can't get back to the Magic Lantern Firmware, unless I install the firmware and then switch over to movie mode.
Very strange.
