747-400F Cargo Doors will not Open!

[Guest Joshuah Wetzel]

Hey everyone,Can someone explain to me how to get the cargo doors on the 747-400F to open? I have programed key assignments two or three times, and it still will not work! I can get the passenger stairs and the tail stand to appear, but nothing else will work! Any advice?Joshuah Wetzelhttp://www.precisionmanuals.com/images/forum/747400.jpg

I think I just found the problem. I was reading PMDG Ops, just before I came and read the last post. I think I know what was wrong. I will post if I need any more assistance. Thanks,Joshuah Wetzelhttp://www.precisionmanuals.com/images/forum/747400.jpg
