Tom - very occasionally I get this error. It was there when I woke up today and WXSIM-Lite had shut itself down at some point. A valid forecast had been produced at 0700. I don’t shut down any WXSIM programs between forecasts - they are open 24/7. I restarted WXSIM-Lite okay.
In an earlier thread on this subject you said wxlini.txt or sitelist.txt were possibly corrupted. I’ve attached these in case they were the culprits. Everything is working okay just now.
