Hello:) I have a windows vista home premium with no upgrades or updated parts. I installed gm doom and put the WADs in the places that you're supposed to put them, but when I go to start a new game on sandbox Gmod crashes and says hl2 stopped working. If I disable the addon but keep the WAD in gmod, it doesn't crash, but none of the items or npcs or anything involved with the mod is there (not a texture problem they're just simply not in the game) same thing happens when I delete the WAD from the gmod file and the addon. I will apreciate any help given to me. Thanks!
