The default database url ( https://junzisun.com/adb/download ) has been moved and the redirection that is given is ignored by JAERO. Also no error message is given to the user to inform them that something has gone wrong.
Really JAERO should follow url redirections but it's probably easier just to change the default address to the new address of https://junzis.com/adb/download
The plane lookup address has also closed and there is no redirection so that's another problem. Currently the only working online lookup I know of is http://www.flightradar24.com/data/airplanes/{REG} and that uses REG not AES
