Invisible Carriers!

[Guest Brooklyn83]

I'm trying to build a carrier-based mission using the latest version of KMD for the latest version of SF2 Vietnam. The KMD tutorial says that when the aircraft's starting icon is over the carrier icon to press alt+D and the waypoint will be attached to the carrier. When I do this I get a message that says "you cannot land at the start position", so I attach them using the dialog box. However when I run the mission, the plane is sitting idle in midair and the carrier is not visible. The catapult doesn't seem to work either as the aircraft flies off the edge of the invisible carrier into the water every time.

 

I've tried using 3rd party carriers, and adding new carrier stations to the map and nothing changes the situation. Can somebody tell me what to do? Thanks.
