i keep gettign an error when trying to boot cs:s half life 2, half life 2 episode one and day of defeat source. team fortress 2 half life 2 epiosde two and portal are all working fine.
now i have tried takign away my over clocks, turning off my anti virus, pluging my modem straight into my computer. and even changing my gpu drivers. and even then it wont run, i tried all those solutions at once as well, and i couldnt find anything in the steam database touching this problem. i sent steam an email and never received a reply either, and its been about 2 weeks now. what can i do guys?
