I followed your link, but it said the topic is locked. Either way I think I've found the problem, I looked into my computer and found that I have two locations where KotOR II is. I don't know how, but I do. There's one spot under Program (x86) Steam, Steamapps and etc, and then there's one under Program (x86), LucasArts, etc. So I'm just going to try to re-install everything (again) to the Steamapps folder and see what happens. I may be back in an hour or two.
