Application has failed to start because d3dx9_29.dll was not found.
If you receive this error message when launching the game then the system you are running the game on does not have the correct version of DirectX or there is a problem with the DirectX install.
To fix this browse to X:\DirectX9 (where X is your DVD drive) and run the DXSETUP.exe. This will install the February 2006 release of DirectX 9.0 and allow the game to run correctly.
