HJG DC-8 panel question

[tinpusher]

Hi all!
Recently I downloaded HJG's DC 8-30, 50, 63 and 73 models, sounds, textures and panels as per instructions.
The -30 and -50 are just fine, however I cannot get any panel to show in the -63 and -73.
I tried all possible tricks to no avail.
Anyone familiar with this phenomenon?

Thanks,
Tin
