Dude, two pages of suffering, and all of because inattention (read FAQ). All you had to do is:
1) Reflash your camera with official canon firmware 109 (and yes, if you already had 109 firmware, you still had to do it)
2) Flash your camera with stable 2.3 build of magic lantern
3) Replace all ML files with nighly build
In my case (Canon 600D) reflashing with official firmware was key part of whole process, it was not working without this step.
