(This is something that I wrote on historyofphilosophy.net.)
There’s still something not quite right, and yet it is possible to download.
I tried playing from this page and nothing happened the first couple of times. I tried other pages and their files played fine. I came back here, and this time it played.
I’d tried here because, attempting to download the file using the Overcast app, I kept getting an error message about an invalid or corrupt (I forget which) file. I tried several times, and always the same. After my eventual success with this page I figured it must be an intermittent error - a bad file cached somewhere? - so I persisted with Overcast and eventually it managed to download the file!
So, if anyone has a problem downloading this particular file, I can only suggest persistence.
