I'm running the latest, 28.0.32. I went back a few versions to no avail. A help request to Audeze got me this: Eric @ Audeze (Audeze Customer Support Center)

Hi James,
Thanks for reaching out. JRiver 25.0.115 is required for Reveal+ to work on most recent operating systems. Previous versions may not load the plugin, so if you can make sure you've updated to at least that version of JRiver, you should be able to load Reveal+.
Assuming you've installed the correct Reveal components into the proper folders so JRiver can find them, any issues you're experiencing should be related to JRiver and its setup.
Beyond that, we'd suggest visiting the JRiver support page to find the source of any issues. They have FAQs, a contact form and a Community Forum that should be able to help.
Sorry we're not able to be of more assistance, but specific platform issues are outside the scope of our support.
I hope this helps!
Eric
