Network Admin cannot access another users site

As the network admin, I was able to access the dashboard of every site in my network. I installed Membership 2 Pro and created a membership level on this users site. Since I did that, I cannot access their dashboard and only their dashboard. Now no other accounts have it activated. So I'm not sure what happened, but I can no longer access their site's dashboard. When I try to go to it, it gives me a screen that says:

You attempted to access the "USMLE Score High" dashboard, but you do not currently have privileges on this site. If you believe you should be able to access the "USMLE Score High" dashboard, please contact your network administrator.

If you reached this screen by accident and meant to visit one of your own sites, here are some shortcuts to help you find your way.
