Star Wars Best of PC

I have been having trouble getting the games to run, i looked on other
threads i tried what it said on a KOTOR thread to go and reinstall and have
swkotor.exe to admin, and compatability with XP. I keep getting the message
Star Wars: Knights of the Old Republic has stopped working. A problem caused
the program to stop working correctly. Windows will close the program and
notify you if a solution is available.
Please Help

not sure if this is causing the problem, if it is i cant figure out how to
fix it
i did a system check, then with to DirectX diagnostic tool and saw this
under soundtab
