do u have half-life or counter-strike retail?
if so did u install it to the right diectory? (Sierra/Half-life/ or Sierra/Counter-strike)
if u did and the shortcut still doesnt work go to ur half-life or counter-strike folder and run hl.exe or cstrike.exe then go to custom game then load esf
also make sure ur up to date on half-life hl1.1.1.0 or cs1.5
