The processing console is not used until you have purchased it and from your description it seems like you haven't. Did you play through the tutorial? Can you move the "crosshair" on the signal searching console? Is that the cooldown you are referring to? Because it is always red. You should be able to scan just by pushing shift if thats not working then maybe try a fresh reinstall. Edit: I was just playing and realized that right shift doesnt activate the scan. IDK why anyone in there right mind would use right shift but i figured i'd say that. lol
