: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...
