Hey ummmm I am having a slight problem running esf with steam... whenever it tries to load the game an error screen pops up and says it can't load my client.dll file... ;( THis is really upsetting me so please help!!! :\
What I done was I went to C: \Sierra\Half-Life . That was my orignal location for half-life before I got steam. In there look for fmod.dll . Once you have found it copy it and move it to your new half-life folder. It should be something like this C: \Program Files\Steam\SteamApps\your email add\half-life . Just paste that file in there and it should work.
