Having only just gotten time to spend playing, I bought the game today, finally!
Being on the beta team originally, I'm already familiar with the game and am itching to have a play with the editor. However, after downloading some of the freebie campaigns/scenarios, when I try to create a new scenario, it's forcing me to place it in one of the existing campaigns. How can I create a new campaign just for me to mess with my own creations please?

Cheers,
Leaston
