So I guess I’m confused why it would work for you, but not me?
I get the timeout error when I try to click https://www.hjpatt-136.umd.edu/Web_Experiments/Slevc/spr/sprAudio.zip (the connection is not secure even though its https?)
The zip downloads successfully when I go to just https://hjpatt-136.umd.edu/Web_Experiments/Slevc/spr/sprAudio.zip (no www)… however when I try to do PreloadZip("https://hjpatt-136.umd.edu/Web_Experiments/Slevc/spr/sprAudio.zip") in my study code (no www) I get the No ‘Access-Control-Allow-Origin’ header is present error… I’m not sure where I’m going wrong here. I tried running the code you posted above that you stated worked for you and its not working on my end (because no www).
