Just a floating cockpit when in cockpit view

Dear simmers,

I can perfectly see the exterior model when in outside view, but switching to cockpit view, looking and moving from the inside in order to see the wings and the rest of the fuselage shows only the shadow of the aircraft on the ground and a floating cockpit! I can't even see the reflection of the strobes on the ground from the inside, unlike the NGX where everything works perfectly. Is anyone else having the same problem? How can I fix this?

Thanks!

Marc
