This smells like a corrupt installation maybe caused by steam ...with "unhandled exception number 72755143 (or some other number)"
Maybe I should post a hint on page #1 to use the nosteam .exe.
OR follow a very early suggestion of BullWinkle and change the script name to Galaxy Explorer and rename all the script files so they won't conflict anymore.
But then people will have two Autotraders ingame and I'd have to manage the coexistence .... naaah
