My son has the supercard dstwo on a DSi and the How to Train Your Dragon game loaded on it. He said the characters should talk in some parts but they don't-he's checked his volume and it's fine. He also said he unlocked a certain dragon but it didn't give it to him (??) I think the hideous zippleback? Anyway does anyone else have these problems and if so is there a fix? thanks ps-he just told me that when he first started playing they were talking but now they aren't anymore.
