Cura - Can't select "Control"

Hey all i’m a new user, and the control button in Cura isn’t lit up and I can’t click it. The last print i was doing I accidenally exited the control window while it was printing and the printer just stopped and I’m thinking that is why I can’t click it. Any solutions to my silly problem?

Edit: Figured it out, The object i was printing was slightly too big. Works great now!

Cool. Happy printing.
