this happens if there is no main_file for some reason. Fixed error message, but not reason why the main_file wouldn't be there. Can be fixed by the user by pressing the pipeline's reset button.

this could have been due to a reboot gone wrong. but perhaps system should pay attention if files do not exist so they can be initialized properly.

think this is to do with an endpoint exception (due to going bigger or smaller than allowable) and wasn't getting caught
