I've tried everything!!
Ok, here's the low down. Before I installed ns 3.0, A friend of mine came over and played c.s. while logged on to his own account. I then logged him off, logged in as me, played the half life training couse, then tried to install ns 3.0. It's started installing to my friend's account, not mine. I can see it when I log on at all. I have tried deleating his folder (firstname.lastname@example.org), installing ns 3.0 twice, and playing HL again and reinstalling. I have no clue what I am doing wrong.
