ok this should go in the other forum but here it is anyways
Windows XP Patch:
Some people have expressed problems in playing Infernal Machine on Windows XP. I too have had this problem, and I found a Windows update that seems to have helped. '327979: Recommended Update' is the one I downloaded. Description: 'This update addresses the "Game Stops Responding (Hangs) or Quits Unexpectedly When Introductory Video Clip Is Played" issue in Windows XP, and is discussed in Microsoft Knowledge Base (KB) Article 327979. Download now to prevent your computer from not responding during video playback.' It worked good for me, so XP users click here
for Windows Update.
