Wikilocs route into Mapfactor

I am trying to download .gpx routes from Wikilocs for use on my motorcycle. The route downloads OK (500 waypoints). I then use Route Importer to convert the file so that I can navigate it within Mapfactor but when I try to load the file from My Places, My Routes, I always get the message 'Unfortunately Navigator has stopped'. What am I doing wrong? Regards Colin
