KML file doesn't load [Track Path 1.02 iOS]

[ISDLdriverGT]

Hi.

I'm trying to make a track using a KML file as the reference line. I have followed all the steps but when I select the KML file in the Track Path App nothing appears. The track fits in the allowed area so I don't think this is the problem.

I have looked for people with the same problem without any success... Any tips or info to solve the problem?
