I'm having problems when downloading 3rd party aircraft. The problem is that the planes are missing the external parts: the skin,engine.wings etc.I'm only getting the internals such as airfreight boxes and the pilot. Some a/c are only showing gauges and no panels, others look like a ghost.I running WindowsXP, Nvidia 7600 GT+, 2 gigs RAM, View Sonic VX2035 monitor. By the way I have used these planes before so I don't know why this is happening. HELP!! Sinr56.
