After opening the gpx file, you have acquired from your phone, with Notepad and compared it to the gpx file from the TGP, the format that they're using are completely different. Please keep in mind that there are different kinds of gpx file formats out there.
To be able to use a gpx format that TGP supports, you can use the GPSies website (http://www.gpsies.com/convert.do
) to convert the gpx file that you acquired from your phone. You can do this by clicking on Choose File and select the gpx file (from your phone). Then, under 'convert to:', select Track and choose GPX Track from the drop-down list. Click on the convert button and you'll be able to see the gpx file being downloaded. Once it's completely downloaded, please open the gpx file with TGP.
You can apply the same thing for the kml file. Make sure to select Google Earth KML from the drop-down list.
By the way, I just sent you the converted gpx file of the gpx (you have acquired from your phone). Please check your email.
