Argh Same deal. I have installed both a different DVD drive and installed that "HiJack." Nothing works for me.. Not HL2, or the online games. Do I have to reinstall with this new drive!? I dont suppose any of you installed a ripped version of the game? I had and decided to buy. Could this be a common trait that no one is willing to bring up? Now Im considering going back.. To think, Steam was designed to prvent this kind of thing.
