:'( :'(All of a sudden my aircraft are NOT Showing in any outside view in FSX \Gold\Accel. 2D,VC Panel work allright,but anything outside is just invisible except the beacon and NAV lights. All the planes show in the menu and when chosen. As soon as I press the FLY buttom and FSX loads my flight the panels show...Then when I go to outside views,tower etc...there's no plane,wing or anything. Only in 3D view can I see these. Help I'd hate to have to reinstall :'(

Although I don't know why that is suddenly happening to you, you don't have to do a complete install.
Put FSX Disc 1 in the DVD drive and select Repair when given the option to Repair or Remove.
Once it is finished, put the Acceleration Disc in the DVD drive and select Repair when given the option to Repair or Remove.

I'm not sure that something in the your fsx.cfg would be causing it, but it wouldn't hurt to do what CoolP suggests. You never know. It could be that simple.
