@mjrii87: please follow forum rules and do not pots in something like this, a 2-year old thread which may or may not have any relation to your current issue and which is also not related to the map editor, which is the current forum. Go seek out current threads in the app forum.
I have the same issue. It seems if you clear the memory on the phone it somehow knocks out the map data. The only way to get it back is to uninstall and re-install the app. This is annoying and the only map navi app that has this issue.
