I can get steam working but when I try and launch team fortress 2 it either looks like it's loading and then stops (see the red light linking on the computer) or it just freezes. But! if I try and launch hl2.exe? by itself it loads what looks like tf2 single player? (maybe it does that when it can't find the cdkey).. What I did was install steam on here and then copy the tf2 game files that were downloaded via steam through windows in the steamapps folder and placed them in here.
