[1.4.1]Turtles won't move

Hey, I've just downloaded CC 1.4.1 and for some reason I can't get turtles to move, they can only turn left and right. When in go into the lua mode and type in turtle.forward() or any other movement command except turtle.turnLeft() and turtle.turnRight() it returns false. However it seems that turtles made in 1.3.x and before still move.

In 1.4.1, turtles require fuel if the config is set accordingly. Look in the config and disable it or give some fuel to your turtles.

Oh yea, forgot about that, now I feel stupid, sorry for the false alarm
