Hey Brad, I am also having trouble with charts. under charts and add ons I cannot expand on the rectangle of download charts. Also, if I click on update, the job never finishes, the bar traverses about 7/8ths of the way across and then stops, I left it all night and still never finished. I deleted and reinstalled the app, and it appears to have dumped all charts that were previously saved. So now I have no accurate position AND no charts. : (
