Error loading model.

Hello !
I’m a beginner for modelling and I’ve just done some headhacking.
After following this tutorial I have compiled the model, and when I try to open it with Model Viewer on Source SDK, I’ve just got the error “Error loading model”.
Where can I see the error in my model ? Does the error come from the QC file? Can somebody help me with it please ?
Thank you.

Can somebody see the .QC file and correct plz ?
Now, I can open it with Model Viewer but now, the head is black and the glass are no textured.
