What exactly is not working? What kind of gpx-file do you have, where does it come from?
The message from the log-file, between import and digger_config.xml, for what file are the three dots (...)? Usually all map-mca-files from MapFactor (like germany_osm_west.mca) don't have an digger_config.xml inside, that's why digger can't access them.
So, can you perhaps provide your gpx-file, I could try to convert it for you. You could contact me by PN.
Thanks. The gpx files are coming from from Garmin Basecamp. The "dots" represent the names of the file structure which i thought would be confusing. Sorry.
