NessAndSonic: I looked it up and it claimed it was on the 2010 version. Anyway, I tried running it again after installing it despite the errors. I'm getting one about DirectX 9 not being properly installed, despite running DirectX web setup and being told it's up to date.
Idarion: The problem with DirectX is that you need the exact same version an application was built with, which the web setup usually does not supply. I've now included the DXSetup that should install the correct version.
Even after installing the DirectX version that was bundled with the fix, I keep getting a "DirectX 9 was not installed correctly" error message. I checked, and there's a D3DX9_43.dll file in my System32 and SysWOW64 directories (I'm running Windows 8.1 64-bit).
Did anyone else run into this problem, and perhaps know a solution? I'd love to play the game without the stretching.
