I am stuck on this case and have tried all walkthrus which have worked for other people, but have also found others are having the exact same problem. I get to see the doctor and am meant to be able to ask him questions about him owning a truck, but these questions do not appear, and threrefore am unable to move on to the next location. I have tried this case 6 times and am finding it very fustrating

Can anyone help me with this??? Is it the game or is it me????
