First of all, you don't need a crack to play CS since there is no CD check for multiplayer. And anyway, you can't play online with a crack because it will be detected as a different version. Go get the latest version of the hl_loader.exe.
This will let you play without having to crack the hl.exe so you can still play online
I don't think there is a loader out for version 1104 but the loader for version 1101 will work. It does say error when launching the game but it still launches.
