All are the latest version. (Version 2.3 Build #133)
Simbrief downloader program as I have always doen which then imports it into the aivlasoft efb. The .efbr file is locate in the create file plan and routing etc is fine. It is just that the call sign is not updated to reflect the new one in the plan. It defaults back to the one previously used in the last flight. Hence, we have to manually change it to the new one.
