How to enable express gate

I have followed the instructions to install express gate, this is a new bb g73jh refurb I got for $850. I have tried to boot into express gate but I can't seem to be able to figure it out. I leave the turbo boost button pressed on boot, I try the holding down the space bar and in desperation I tried all the hot keys while booting and nothing gets me into express gate. Can anyone shed any light into the matter, maybe there might be a bios change I need to activate or something. The only thing I get is the ASUS animated boot screen with sound and then windows is starting but no express gate at all.
