Eagle tree logger problems

[johnrobholmes]

I can get data from the recorder. I save it, it shows data. I try to reload the file and it shows no data, although the file in fact does have information. What am I missing here? I have tried many ways and multiple times of retrieving old data logs from my new logger, but when I download them originally is the only time I can see the data. I have to be making some simple mistake.
