 :trooper: "Look Sir, Droids."
  
 
  
  
    What are your full system specs?
 
 Have you tried updating your graphics drivers? Or using an older version? That might fix it...
  
 
  
  
    **UPDATE**
  LucasArts has a page in their Tech Support section about this - 
http://support.lucasarts.com/trg/tgd.asp?id=2399&g=120&s=4) - see if that helps...
