Missing texture coordinates for channel 0 Fbx and XNA 4.0

I'm getting this error while trying to load a model in XNA 4.0 : Error 2 The mesh "transform1", using SkinnedEffect, contains geometry that is missing texture coordinates for channel 0. The model was dxf format then I upload it to maya then I added some skeleton and some texture (viewed it on the UV) but I still get this error.

this is the load function.

 protected override void LoadContent() { // Load the model. currentModel = Content.Load<Model>("myModel"); // Look up our custom skinning information. SkinningData skinningData = currentModel.Tag as SkinningData; if (skinningData == null) throw new InvalidOperationException ("This model does not contain a SkinningData tag."); // Create an animation player, and start decoding an animation clip. animationPlayer = new AnimationPlayer(skinningData); AnimationClip clip = skinningData.AnimationClips["Take 001"]; animationPlayer.StartClip(clip); } 

this is the draw function :

 protected override void Draw(GameTime gameTime) { GraphicsDevice device = graphics.GraphicsDevice; device.Clear(Color.CornflowerBlue); Matrix[] bones = animationPlayer.GetSkinTransforms(); // Compute camera matrices. Matrix view = Matrix.CreateTranslation(0, -40, 0) * // x, y, z Matrix.CreateRotationY(MathHelper.ToRadians(cameraRotation)) * //rotate y Matrix.CreateRotationX(MathHelper.ToRadians(cameraArc)) * //rotate x Matrix.CreateLookAt(new Vector3(0, 0, -cameraDistance), new Vector3(0, 0, 0), Vector3.Up); Matrix projection = Matrix.CreatePerspectiveFieldOfView(MathHelper.PiOver4, device.Viewport.AspectRatio, 1, 10000); // Render the skinned mesh. foreach (ModelMesh mesh in currentModel.Meshes) { foreach (SkinnedEffect effect in mesh.Effects) { effect.SetBoneTransforms(bones); effect.View = view; effect.Projection = projection; effect.EnableDefaultLighting(); effect.SpecularColor = new Vector3(0.25f); effect.SpecularPower = 16; } mesh.Draw(); } base.Draw(gameTime); } 

PS : 1-My knowledge with Maya & XNA is very limited cause I used to use OpenGL/C++ for some time.

2-Also I change my Content Processor to SkinnedModelProcessor not Model - XNA Framework. thanks in advance.
