I currently have the version 184.108.40.206 installed, and I cannot figure out how to update to the latest version (220.127.116.11). Every link I click either sends me to the default dashboard for my wordpress site, or to some random page that doesn't help on WPMU Dev.
Clicking "Install Protected Content" on this page: https://premium.wpmudev.org/project/protected-content/#usage
Redirects me to the WPMU Dev Dashboard "Updates" page, which shows the plugin, and allows me to click to update to the latest version, which redirects me to the following page.
Clicking "Download Now" on this page: https://premium.wpmudev.org/wdp-un.php?action=details&id=928907&
Just opens a new tab of the same page.
