It's working for me: follow the instructions. Start the game, wait for the main menu, launch R6_X.exe, click on No, return to your game and wait 30 seconds. The hack will launch alone, you will notice a message on the top of your screen in the menu of the game.
That's all! No need to press F1, you launch a game (situations, pvp, coop whatever) and you will see the magic green rectangles!
