you should not need to reinstall, in fact it is advisable to not only download the .dll files but rather install the whole DirectX 9c into your windows system (for XP this will not cause any issues and the newest (i.e. November 07) release of DirectX 9c should also be compatible with Vista.ok, i have this problem and i'm slowing reading this thread, trying to fix it,lol. After i download these DLL files,do i have to re-install the whole game? or just add the patches?
