Triple post... terribly sorry. This is new... "Half-Life requires Service Pack 3 or above." Yes I'm using Windows XP as my mode. Windows 7 gives me an "hl.exe experienced an error... blah blah blah" message. As does Windows Vista. Windows 2000 does it, but then it gives me a "please insert the CD" message. However, it DOES go to the menu (which is slightly garbled in terms of graphics). I'm updating to 1.1.1.0 now. Ok... more problems. When I start a game, it goes to my desktop in 640x480 mode, and starts playing the sounds like the game is going. Pressing escape goes to the HL menu, where I quit the application.
