It seems that whenever I load up certain custom maps, the loading gets to 'Verifying resources' and then CS just closes. It doesn't actually start downloading. I have no idea why I get this error, and it's really annoying because I can't play the maps I want to.
You may be possibly missing a file, this was happening to me for a while, i just told Valve/steam that it was doing that and they said have you updated recently, and so on, they sent me a new file their new update wasnt downloading, It was mainly happening for fy_ maps but the custom maps wouldnt even get passed Verifying Resources just tell them, they'll sort it out or possibly re install it
ye this was happening to me to so then i deleted steam and was going to re-install but its been like months cause im 2 lazy to install again but will soon and hopefully this error is fixed ye no
i have never had this problem. so i dont kno why. also make sure cl_allowdownload is 1. or you firewall/router blocking to download custom maps?
