Textures don't appear on mesh

I did indeed post a thread on the mini cup I've been working on. I came across an issue though. The textures don't apply to the mesh. For some reason the only texture that appears is a fire extinguisher. None of the other textures load. Also, it doesn't show the orange no material texture. It instead just shows a dark gray material. Any help?

 

Indeed it is. Heres what I meant by the only texture showing was the fire extinguisher.

The seat is suppost to have a leather texture, and the interior should have a metal texture applied to it. I even opened it up in the material editor in beamng and it said it was mapped correctly to the texture.
