I just upgraded to XP from 2K, and now, when I try to launch HL or any of the mods, I get "Half-Life has a known compatibility issue with this version of Windows. For an update that is compatible with this version of Windows, contact Sierra." Well, I reinstalled HL, downloaded and installed all the updates, and I still get the message. If I continue, and try and join a multiplayer game, I get some .dll error message. Anyone know what gives?
