Every now and then Maya gets its knickers into a knot with mia_material_x and I normally get the following set of errors:

// Error: Object 'mia_material_x_qualityMenu' not found. //
// Error: AEhardwareTextureMaterialChangedCB SM_WingFlaps.diffuse SM_WingFlaps.message; //
// Error: Wrong number of arguments on call to AEhardwareTextureMaterialChangedCB. //

The result is that I can't assign any value other than "None" to the texture channel attribute under "Hardware Texturing" on the material and the mesh will appear black in the viewport.

The only way I've found so far to get around it is to restart Maya. Is there is script or something I can run?

This question has cropped up early December last year but that thread kind of died.
