I have several courses saved and when I open them from the list the route appears on 'zoom to course' but nothing is there on 'view details' other then the green start and red end points. These are courses saved for a weeks ride that I MUST HAVE TO BE ABLE TO DO THE TRIP! Where are they and how can I edit and resave them?????
I believe that the data is still there. It appears to be just a rendering bug (the line that you want to follow isn't there). You don't need to resave them, just upload them to your device and they should be fine. If you don't believe me, you can look at the links from this thread. If you click the first link you will see the start/end points. If you click the second link (the data for that course), you will see the gps data is in there.
