I Can Access The Network Dashboards But Not The Websites

I am able to see the dashboards for a multi-site install, however, I can't see the websites themselves. This happened when I installed s2member plugin and activated it on a website in the network that was running WPMU Membership Plugin. Please see if you can help me get the websites to show again.

We have tried to change the htaccess file to the default, removed WP Super Cache and redoing the DNS A(Host) back to "*" (which was working fine).

the website is: http://wun.leadwithanedge.com
