This is strange. This could be a problem related to sample rate. PataTracker can only exports at 44.1kHz
I can not access the link you posted. I think you need to make that folder public
How about this - I think I made the folder public?

Here's the file with the public option turned on:

I haven't changed the sample rate, btw (is there an option to do so?). I just opened the Tracker, made a pattern, and exported the result as .WAV. Was a strange thing to hear.
