I recently installed MSTS Bin and I really enjoy the new features, especially cab switching and the RE improvements. But I have a problem with some addon railcars- some of the textures are invisible. You can see this in the attached screenshot of my Class 50. This also occurs with some 3DTS freight cars. I am fairly sure this wasn't the case with my original MSTS installation.

Any ideas? Thanks in advance.
