WPMU DEV Dashboard suddenly broken

Not sure what happened.

I was just toggling Jetpack on and off for another issue, then made a Snapshot backup, and now I can see a PHP error (Invalid argument supplied for foreach() in /home4/gourmew0/public_html/wp-content/plugins/wpmudev-updates/update-notifications.php on line 1793), and am told I'm not a paid member.

This is not happening on other WPMU-installed sites.

See screencap.
