I have had this software for a good while now and had no issues until recently. I don't know what caused it but no airports are available in its database. I rebuild the database several time and noticed it is reading my scenery data from a non existing directory. This causes EFB to have no airport data available. Now why did this happen? No idea. How can this be fixed? Its not looking in the default directory, I attached a pic to show what I mean.
