Caches along a route using Delorme SA+

[+Frank and Peggy]

I prefer to use Delorme SA+ instead of Google earth to generate my routes and have been unable to get geocaching.com to accept either my .kml or .gpx files. After saving my routes as .anr files, I simplify them to 100 points and export them using gpsbabel to create .gpx or .kml files. When I upload a .kml file, geocaching.com says, "Sorry! We encountered an error when requesting that page!". Uploading the .gpx file simply returns me to the upload page without doing anything. Has anyone had success loading files created by gpsbabel?
