Are you talking about when you have to break in to his home, after Lily stays at your home? After talking to Alice, you need to visit Bront's shop(Blue and white striped shop) and buy a lock pick. Then at night, visit James's home
Are you using an older save from a older version or did you start a new game and jump straight to act 2? Because it could be a bug from an older save file.
It's probably a bug with an outdated save file. Theres an option when making a new game, to jump to the start of act 2. Try that and you should be good.
