Looks like a bug, thanks for reporting it. We think we've fixed it, just in time for tomorrow's release. The bug only concerned the presence of aircraft files exported from previous versions of SkyDemon.
We plan soon to create a page on the site devoted to aircraft files, designed as a central repository of some of the most popular aircraft models.
Fantastic news on all counts.
Thanks. :-)
