In case you guys are having trouble with getting the experimental build to work, here's a couple of suggestions : 1.- If the original method doesnt work for you (you're not getting the option to select the experimental build at all), delete local content by right clicking on the game in your library. You'll see the option. 2.- After you have unistalled the game, go to properties and go to the beta. Select it, it will ask for a code. Whatever you enter, it wont work. What you need to do is just select the experimental build, withouth typing anything, close the window and click instal on your game. Your file should be 1.2 gb-ish big. Thanks to daniel on the forums for helping me figure that out, although it was mostly me and my curiosity skills with which I've trashed computers.
