There is  such item in the installation instruction:
"Make sure you are running Canon firmware 1.1.3."

But my 6D has firmware 1.1.4

The 1st quastion : Can I use current version of ML with 1.4.4, or I have to downgrade firmware to 1.1.3 ?
The 2nd quastion: Is there (in the 1.1.3) different languages, or it is English version only?
