Hi, the issue reported here in various posts about the inability to import simulators / airport data in version 1.60 has been fixed. The new version is 1.61 and should be available to you soon. Some more details here:
FS Logbook Editor 1.61 – RELEASED!
and on product page: FS Logbook Editor
Once again, I am sorry for this stupid bug and for how long it took to fix it.
