The following code is a complete XNA 3.1 program almost unaltered to that code skeleton Visual Studio is creating when creating a new project.
The only things I have changed are
imported a .x model to the content folder
of the VS solution.
(the model is a simple square with a texture spanning over it - made in Google Sketchup and exported with several .x exporters)
in the Load() method I am loading the .x model into the
game.
The Draw() method uses a BasicEffect to render the model.
Except these three things I haven't added any code.
Why does the model does not show the texture ? What can I do to make the texture visible ?
This is the texture file (a standard SketchUp texture from the palette):
And this is what my program looks like - as you can see: No texture!
Find below the complete source code
of the program AND the complete .x file:

graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
}

GraphicsDevice.Clear(Color.CornflowerBlue);
Matrix[] transforms = new Matrix[newModel.Bones.Count];
newModel.CopyAbsoluteBoneTransformsTo(transforms);
foreach (ModelMesh mesh in newModel.Meshes) {
foreach (BasicEffect effect in mesh.Effects) {

effect.TextureEnabled = true;
effect.World = transforms[mesh.ParentBone.Index] * Matrix.CreateRotationY(0)

effect.View = Matrix.CreateLookAt(new Vector3(200, 1000, 200), Vector3.Zero, Vector3.Up);
effect.Projection = Matrix.CreatePerspectiveFieldOfView(MathHelper.ToRadians(45.0f),
0.75f, 1.0f, 10000.0f);
