I wish I could. To my knowledge, I didn't do anything differently. Basecamp opened up fully, I followed the procedure and loaded three maps (+My Trails) handily. However, I am trying to load more three more maps now, without success. I get the message "All maps available are already installed" or similar wording. Yes, I did run the installer. I am a little stumped; I had virtually no problems with my older Etrec 30, and using an earlier version of Basecamp.
