All my pro sites settings have been reset as if I just installed this for the first time.

I had pro sites completely setup with levels , payment gateways, premium plugins, etc. Now all of those settings have been reset as if I had just installed the plugin. The last update for Pro Sites plugin that I did was on March 6 to the latest version, which appears to be 3.4.3.3.

No one else has access to this network. Any thoughts on this one?
