I have downloaded Alan Wake Bright Falls thru GOG downloader, version 2.0.1 something, and after installing, etc, went to start and it won't start. i get an error message that i am missing d3dx9_43.dll file. I have DirectX 10 on my system, Windows 7 with ATI Radeon HD 5450 graphics. What is the problem? Do I need DirectX 9?

disregard, i downloaded an older direct x and it works
