I have previously successfully loaded the maps from his link to my new etrex (thanks Ent for all the hard work) and have been having a play. However, when the gps is connected to the computer and I try and import the tracks into google earth, I get a message "loaded no data".
When I try and open the files on the computer, I get a message "disc image file is corrupted".

What am I doing wrong? Can someone please help me, given that my tech knowledge is very limited


Thanks in advance for any help.
