Hi, as mysteriously they disappeared, just after installing two new add on airports and re-building the DB, all has been fixed. Don't ask me why; it can' t due to the new airports, since lots of other times I rebuilded Plan G DB without any issue.
    Thanks and regards,

Hi, for some mysterious reason, Plan G doesn't load anymore all the PrD v4.5 airports from the 000 to 1007 base folders. My OS is W10. It load down to ORBX folders. I tried your last version too, but to no avail.
  Thanks for any help,
    regards,
