Cannot load add on aircraft

[ablackhawk2 0]

This is very strange but my problem is that FSX will only load the aircraft that I have chosen. While in FSX when I want to load a new aircraft from the aircraft menu = it freezes FSX and I have to use control alternate delete to get out. Everything else works except the aircraft menu. Help please. Am running windows 7 64 bit. It has been working fine then this happend to me.

Did this always happen or did this start to happen after you installed a new aircraft add-on? (If yes, uninstall the add-on and check everything OK again.)Cheers,- jahman.
