New update cause 3ds max to crush on startup

I installed 3ds max 2014 and updated my grapich card (635M) to the latest version.
When i opening 3ds max it crushing on the logo screen as it “start 3ds max…”

the solution that i found is to downgrade the driver to 314 and that solve it but it seems that a new problem is apeared becuase its old driver and i think mental ray 2014 need some file in the new driver.

(when 3ds max launch it says : standard startup file ray3rc is not found)

does any one know what can be done ? becuase this is kind of pointless to fight it .
