Hi,
I have a similar problem going on. I don’t think my experiment was able to access the zip file properly. I followed the instructions in the documentation and uploaded a zip folder containing audio files(.WAV) to a school server along with the .htaccess, which the IT department said should work, but now I’m not really sure what’s going on. The debugger didn’t mention any type of error occurring as it was running the experiment.
The link to my zip file is https://mfile.umich.edu/?path=/afs/umich.edu/user/t/j/tjuan/Public/Spanish%20Pupillometry%20Project%20Resources/Audio_Files.zip
