I have a file full of waypoints and tracks exported as a kml from Google Earth. BaseCamp spins for a while on import and then complains that the "kml file is not a valid KMZ file and could not be opened".
I used GPSBabel to convert the kml file to a gpx file, and BaseCamp spins forever with a beach ball. I have to kill it.
I opened the gpx file in a text editor and the syntax seems perfectly fine. Any ideas what I can try?
