You have to have original HL? I have 2 retail versions of Halflife CS, and the Halflife CD that comes with the ATI Radeon 8500 card. None will allow Day of Deafeat to work. ? Thanks.
I do have the latest version of CS. . When I install it, it asks for the Halflife directory, but since I dont have one, it defaulted just to "C:/", I then clicked browse and went to the CS directory where I installed it all. Did not work. .
