Launching Game With Razer Cortex Does Nothing

Hi,

Whenever I try to launch my games, such as Team Fortress 2, Razer Cortex does its normal thing, it releases MBs and then normally when it goes to the game desktop and opens the game, instead, now what it does, is it decides to just not launch the game and I can't play it with the most performance that I can get out of it. This has been going on for about a week and in that time I don't remember changing any settings, I have tried repairing and uninstalling the game.

Thanks.
