Hair dissapeared on Reference model

[Filmguy]

Hi Guys. Have been animating a reference model /dog character for a commercial with hair guides. I made a slight change to the emdl (just adding a few more properties to the root) As soon as I came back into the scene file the hair dissapeared from the virewpoint and render. Switching back to RES 1 doesn't even make a difference and same problem persists.

Any ideas?

Thanks

Ah. Just re saved the source model and the hair updated in the scene.
