I just got this game for christmas and have just installed it.  It doesn't work though.  I always get the error after first two intro videos which says" Star Wars: Knights of the Old Republic II: The Sith Lord has encountered a problem and needs to close.  We are sorry for the inconvenience."   and at bottom it says the usual "send" or "don't send".  I have everything right for hardware but the graphic thing which is "SiS 760" and the ram which is a bit low with 384mb. 
  
I suspect it is the SiS 760 that is causing it but not sure.  
  
here are the rest of specs
