I'm using 3.2.1-r2 as well, (MacIntel, AC3D 6.7.15).
Your ac file actually exports nicely here (after pointing a few objects to the included texture).
Animated parts do move when viewed in Ben's little ObjView app.
I didn't test it in x-plane yet (will do tonight) but it looks quite allright.
Here's my exported obj file with my XP plugins + dataref files from the latest XP release:

I'm unsure if the plugins I use are downloaded or if I compiled them myself from source.
I can only check that later today. You may want to try them out to see if they fix your issue.
P.S. I wasn't aware that one can add text to the Animation folders name. One never learns out....
cheers
