One of my Sims keeps crying and refuses to use a computer. He's an Investigator and I've been trying to get him to write up a report on his laptop, but the action disappears. The same happens with the desktop computer. He won't play computer games or anything else. He's not a technophobe, and he's used computers before on this lot without a problem. And he's "elated", but still crying. I'm very confused. What is going on here?
