Need help posting a streaming file to AO3

[alba17]

I don't know what I'm doing wrong, but I'm trying to post to AO3 a streaming file from Mediafire and it isn't working. It looks right when it's posted - I'm using the code that AO3 provides and filling in my file link from Mediafire - but when you click to play it, you don't hear anything. I made sure the volume is all the way up. I've used all the variations given on AO3, but none of them play. No solution comes up when I Google it.

Is there something wrong with the link to Mediafire? Or what? I feel like there's probably a simple solution, but I'm stumped.

Code:

It looks like this, but doesn't play, as you can see if you try:

[Psst: First of all, I'd like to sincerely apologize to the poor Audiofic Archive archivist that gets stuck with this job. Feel free to contact me at Hananobira @ Gmail if you have any questions.

I sat two non-fannish friends down at the microphone and forced them to podfic with us, so they won't have tags. Can I have two created for 'reader:Brandy' and 'reader: Jennifer Hunt', please?

Thank you! ::blows kisses::]
