Hi, I have exactly the same problem and specs as meddelertobi, except I have the english.big file, so it's not that. I was wondering if it has something to do with dual core of some brand or anything hardware related ? Also, strange things happen, like the main menu looks just like the normal HW2 menu. And when I delete the old music.big file, I won't hear the SW music on the main menu. Here's my log. it doesn't say there's a crash but it crashes still. I don't understand, it used to work on my machine... Also, I have all the original HW2 .big files in the Data folder, because when I try to get rid of them, the game won't launch (at least that's true for english.big and Homeworld2.big) Fri Nov 02 13:43:11 2007 Loaded Archive: 'Homeworld2.big' UTIL -- filepath failure, path doesn't exists 'Z:\Program Files\Sierra\Homeworld2\data\locale\english' Loaded Archive: 'english.big' Loaded Archive: 'Planetpack.Big' Loaded Archive: 'SWSOUND.Big' Loaded Archive: 'SWMUSIC.Big' Loaded Archive: 'SHIPHODS.Big' Loaded Archive: 'CORE.Big' Uing ..profiles\ for profiles folder Cannot overwrite function SobGroup_SplitGroup Cannot overwrite function SobGroup_SplitGroup Cannot overwrite function SobGroup_SplitGroupReference GAME -- Using player profile Mtz Changing from a 32 bit colour depth in winNT (5.1 build 2600), Service Pack 1 Using NVIDIA Corporation's 2.0.3 GeForce 7900 GS/PCI/SSE2 renderer (Suspected driver is nvoglnt.dll 6.14.10.9371) Loaded Archive: 'englishSpeech.big' Failed to Load Archive 'Z:\PROGRAM FILES\SIERRA\HOMEWORLD2\DATA\Music.big' SOUND -- created destination [ fdaudio ], handle [ 4 ] with [ 48 ] channels created SOUND -- created destination [ fda streamer ], handle [ 5 ] with [ 8 ] channels created Build name: The Dust Wars - AutoBuild3569 - Ordered by smmatte Built by : mrbuild Data path : Z:\Program Files\Sierra\Homeworld2\data Movie::Play : Unable to find sound file data:Sound/Music/ANIMATIC/logo Resetting fp control word.
