and welcome to LucasForums.
I think we'll need more info before anyone can provide you with real assistance. Have you clicked on the Update button on your KotOR launcher to make sure you've downloaded and installed v1.03? Alternatively you can download the 1.03 KotOR patch from http://www.bioware.com/games/knights...pport/updates/
Also this thread would likely get more attention if it was posted in The Work Bench
forum as that is the place dedicated for members having technical difficulties with the PC versions of the KotOR games.
