I can import kml and get the track layout but with no height added. I have converted the kml to csv and try to import but nothing happens, it's as if its loaded up but the builder remains empty. Is this a common mistake or are the GPS co-ordinates just wrong? I only have a few lines compared to the test csv's from bobs gps folder. It is the latest version of btb and windows 7 running in XP compatability. (I know it isn't supported but it seems to work fine so far) Thanks for your time. *EDIT* Could a mod move this to the BTB forum, just noticed it!
