I am playing LEGO Harry Potter for the first time. I am stuck and no search gave me an answer that worked. So, I am relying on you guys to help me out.

I haven't finished the story levels yet, I'm in Year 4. I have Reducto and unlocked Barty Crouch Jr at the Quidditch World Cup, so I'd like to go ahead and start doing some free plays.

I see the postcards near the staircase in The Leaky Cauldron that allow you to freeplay the story levels, but I'd like to roam around Hogwarts some.

How the heck do I do that? Is it not possible until you've finished the story section, or am I just totally lost?
