HELP with megatrucking mod

Hi Guys: downloaded the megatrucking mod and the saved game, and it seems to work ok, hired a utility ship went to the common metals processor had the utility vich.dock with the processor, tried to sell some cargo and nothing… nothing on the screen where there should be @400,000k worth of metals. at least according to the readme file anyway. So did I miss something? and where do the pog files go? are they supposed to go to any particular folder or just stay in the zipped format in the mods folder?
Also if I just decided to sell the megafreighter and down sized to a regular freighter could I do that?
thanks for the help
