Upgrade to update WPMU Dashboard

I see that there is an update available for WPMU Dashboard, but it says I have to upgrade in order to update. There is a link on the word "upgrade" but it just takes me to this page:

I also seem to be missing some navigation under the WPMU DEV Dashboard navigation bar. I was going to search for the Update section, to see when it last synced, but I don't see that as an option.

I'm confused. Help?

I went ahead and activated support access.

Thank you,
