BRouter can't find data file.
I set up Locus Map with BRouter for off line navigation and literally overnight I can no longer get BRouter to create a route. A yellow box comes up saying "Missing data file for offline routing, download?" BRouter then takes me to the data screen, I select a point, but it still won't create a route. I uninstalled BRouter and re-installed, but it made no difference.
Is there an obvious setting that I am missing? What could have changed overnight?
