I keep getting the following message when starting passengers boarding.

Please download and install the latest Stand-Alone Addon Manager Etc

I've re-installed it 3x now with still the same effect.

This error indicates the scenery AFCAD has an error, like overlapping nodes, orphaned nodes, unconnected links, unreachable parkings, etc. You might try to fix it using the ADE or AFX "Fault Finder" options, or at least having an idea what's wrong with the AFCAD, and report it to the developers.
