KC, the door issue is probably on my end. They function normally until I fly.. After that, I can open them by clicking on them in the VC, but they very quickly close on their own. I've seen this in my sim before, though, so it might be a conflict of some sort on my machine.. My installer reads version 2.0.0.24, size 348mb.
You're not landing on a fuel bay parking spot are you? There's a very well known bug in FSX that causes the door animations not to work around fuel squares - they open when asked, then instantly snap shut again.
Try moving to the other side of the airfield and seeing whether they work there.
