I've used eCoach twice now, the first time just to play and test it, the second just, on a little jog. The first time worked fine could view the map, graphs, data, etc afterwards. But it didn't save that data when i started a new activity, it just disappeared! Then today i got to the end of my jog, which it had tracked beautifully, and it gave me a message that it couldn't save the file or some such nonsense. Anyone else had this?
