I actually bought it before I even downloaded the game, because I've been such a fan of the other four VVs. But I just wasn't paying attention to where I should download from and clicked the "demo" button, so that's the one I opened first. Then I realized it was the wrong thing, and re-read my activation email.
Too late, though, unless I want to start over. It's not a huge deal to me, really, and I doubt I'll start over.
