First of all I apologize for my bad english. I am having this problem both in the previous version of the mode and in the current version. There is no effect on playing, but I constantly get these kind of error messages on the screen and it makes me very uncomfortable. Please help me. :-\

Re download and extract the game files from Moddb. Also, are you using DirectX 9? If not, you should. Shaders don't work (well) on DX7. You can change that in the settings before you launch the game.
Thank you, I already use DirectX 9. As for the other thing you said, I downloaded it and copied it, there were 2 new files so Shader so I was very hopeful. But unfortunately it did not work (I tried by opening a new save)
