Ozi explorer is hanging on the boot screen. Help!

If you plug your unit into your computer and go to SDcard \ ozi \ data you will find “CEtracktrails.trb”, if you delete this file and try loading ozi again, this should sort out your problem. Failing that try again plugging your unit into your computer and going to SDcard \ ozi \ data and deleting “CEwaypoints.wpb”. Try one then the other, do NOT delete both in one go.
