hi im new to this and i have the helf-life day one reatil version installed in my pc. but since its windows xp it doesnt work. so i bought the RETAIL counter-strike and installed it. then i installed the latest version of esf on your site. i went to counter-strike, went to custom mods and activated esf. but whenever i start a game it doesnt run, lan or anything. the launcher itself doesnt work so i have to activate it from the cs menu. do i need to upgrade it to v1.5 or something? please help
