Error on Steam Play

I just tried to start the game on Steam and got the following message: "ERROR: Failed to load 'shaders\FixedFunctionShaders.shaderLib'. Engine will not run." What is the solution?

    Have you tried deleting it and reinstalling? It sounds like the install just didn't copy down all the appropriate files.

  • Yes, I did. Twice. I dunno.

    There are a couple things that can help here:

    1. Is the game installed on the same hard drive as Steam and Windows? It may not be correctly finding the files it needs.
    2. Verify the integrity of your game cache (
    3. You may need to reinstall the drives for your video card and directx so that the game can locate the files correctly.
