Hi, Having a little different problem than others. After a failed download, I foolishly took the card out and deleted the map folder on my sd card. ( I had to do it with windows because the N800 refused to do it as read only files). Now map won't launch. It starts then fails returning to the home screen. I've uninstalled and reinstalled map, but still won't launch. I've even reflashed my N800, which recreated the map folder on the sd, but map still won't launch. Apparently, it's a card issue, even though the N800 reads it fine. The next step, I guess, is to reformat the card. Anyone else run into this and able to fix it?
