Having upgraded to the latest version, I can no longer save and load routes. If I save one, quit and restart the application and attempt to load it again, nothing happens. If I try again, I get an unhandled exception error

************** Exception Text **************
System.NullReferenceException: Object reference not set to an instance of an object.

plus a load of other stuff.

Think I'll have to downgrade to a previous version until this is stabalised.
