snapper 21

Hi everyone, I have downloaded the new weapons pack and have installed it in my Wings over Vietnam game and everything seems to work fine. Have also installed in a second version lots of modern aircraft, when I go to the create mission screen and select say A-10 no date comes up, I thought I had read somewhere this can be changed, does anybodu know what file I change? Thanks for your Help Snapper 21 P.S To all the plane and weapon pack creators YOU ARE GODS!!!
