The data looks like this:

110.442
2013-01-06T17:29:34Z

113.776
2013-01-06T17:30:04Z

114.252
2013-01-06T17:30:34Z

The software seems happy to select the data, but then never plots or shows a track... it seemingly does nothing. There is no processing or acknowledgement of the data.

I'm going to try stripping off the headers to see what happens.
