Cyberface Editing: Problem With Blender

Hi guys. I got a problem. I started editing cyberfaces a couple days ago, I edited Nikola Vucevic's 'cause I wanted to create my CF...I watched some tutorials about editing the CF textures. I hadn't had any problem with that. After that I tried to edit the headshape with Blender following JaoSming's videotutorial, but I can't do this:

Can somebody help me? I'm a kinda desperate 'cause of that!
