I'm encountering difficulty importing a kmz (or a kml) file from either Google Earth, or the data that I originally loaded into Google Earth. Both result in "not a valid KMZ file" note from Base Camp (version 4.2.4 on Mac 10.6.8). KML file is 4.2MB, KMZ is 475KB is there a size limit for Base Camp? Or some other reason why this won't import?
