all i did to get steam to work with no probs, was download and install steam with the CS cahce. installed it. updated game list with all on my computer. copied my entire half-life folder from the main directory (nonsteam) then downloaded the 2.8 update and installed it to the steam directory. i have had no probs. it works wonderfully. now if they could only get the whole NO C-D thingy fixed when running CD. and open GL works still for me.i am using Nvidia mx440 64MB by PNY vertoCeleron 650MHZ WIN XP
