Song Download not working on Mac

[nevermindthegrunge]

I purchased the app from the Apple App store so it was already installed into the applications folder by the App Store download. See attachment.
Still not working. Tried setting my default browser to Firefox and it does the same thing. Click on the link, the iReal app gets focus but the song doesnt appear. I also tried sending an email from the ipad app, opening the email on my desktop, clicking on the link on the web page that it opens and that doesnt work either, same thing, song is not loaded into ireal.
Can I try anything else?
Thanks
Mark
