Are all the steps included in your description below?

Using the two knobs on my CNvXC vario, I download the igc file to a USB
drive, plug that into my laptop, and upload to Skylines.aero and to
OLC.Â* Never a problem other than OLC's silly requirements and demands.

Hi

I downloaded a flight from my Clearnav vario with IGC logger for the first time.

OLC says it is not a IGC file.

Advice are welcome to solve this problem.

Thank you.
