It appears that you don't have DirectX 9 and DirectX 10. M$ really messed up Windows 7 by not including DirectX 9 and 10. So I suggest you go to Microsoft's website and download directx 9,10 and install them. It should work now B)
plz renew the link for the add-on... It gives the error"This page cannot be found" thank you, neo for making the Vista RTM boot screen. I really like it.
