The objFile line looks fine, and that's usually the one that causes trouble. If you want to send over some files, I can have a quick look - I won't post my e-mail address here, but you can get it from my contact page.

Incidentally, I see all your rotation orders are the same, which will give you problems. You would normally have the twist axis as the first in the list, followed by the most used rotation second (academic for most aircraft parts). Assuming this is a conventional aircraft, modelled with the fuselage along the Z axis, and the wings in the X, the flaps, ailerons and elevator would want to be xyz, ie twist along the wing axis. The gear would depend on how it opens, whether you want it to be steerable etc.
