thank you that was the Problem

All I see when I hit "play" is "start Campaign", "Load Game", "replay Game", and "back" buttons

SO does that require more than the Transport Belt repairman level of purchase? and if it does is there some way to upgrade rather than having to spend another 27$

I just bought and played through the campaign and was told about the free play mode by someone who introduced me to the game but am unable to find the place to start a freeplay game. where do I find it or what am I missing
