Peninsula Corridor: 07 Mission bay Hauler

So yesterday I was running the above scenario and I wanted to start it over. So I backed out of the scenario and the Sim completely, used the bat file to erase the loaded Blueprints. (I always do this when reloading a scenario because if I don't I loose details in the route). Well I go to reload the scenario and it says game error locomotive ran out fuel instantly. I have a back up of the scenario and copied that over but still no fuel. Since it's a career scenario the save feature is disabled even though the scenario is unlocked in the editor so I can't change anything. Any ideas how this just happened or how I can fix it?
