Just a tho't here. Since you say you can see your wife's pc but cannot access anything on there (and it works OK the other way around) I would concentrate on the permission settings on her machine, making sure things are set up ok on that end. If you're able to, disconnect from the Internet (don't want anyone hacking around) and start with giving a folder full permissions to "guest" and work backwards from there. When I do this, I keep notes on whatever I do so it's easier to undo any damage later on.
