I'm getting very frustrated. This problem happens almost every time I use the software. When I save a route or session the software locks up or crashes and has to be restarted. My last extended database repair was done yesterday and when I went back into my session names on assets some changed. I am not sure if this is a New Era software problem or a problem with my operating system not working right with the trainz software. I am running Apple High Sierra on a Macbook Pro. Has anyone experienced this problem?
