help with vrzoom explorer own map

[Oakridge]

 hi
Im sure there is a simple explanation
I make a ride on my macintosh on my maps
Follow all the instructions and save a .kml onto my desktop
when i try to upload on my Virzoom account I get this message


no such child: {http://www.opengis.net/kml/2.2}LineString

what do I need to enter on location box
I would love to make some of my own rides
thankyou
Steve
