Maybe it was a problem with my browser? I cleared IE's cookies and cache, closed and restarted the browser but the problem didn't go away. I tried accessing Google.com from my other browsers, in Chrome 22 and in Firefox 15, but both returned the same All Access Disabled message. Chrome provided a little more information than the other browsers, something about an XML style sheet not found but nothing helpful.
Since I'm on a MacBook I decided to boot into the MacOS X 10.8 and see what happened. I opened Chrome for Mac (I assume the same version 22) but I got the same problem. At this point I was getting a little upset so I didn't bother to check what Safari would do. I booted back into Windows but Google.com continued to show All Access Disabled in IE9. I didn't have any additional networks to connect to rule out my connection. I seemed to have ruled out browsers being the problem.
Maybe the problem was with my Google account? I went to my desktop that had IE9 open on Google.com, refreshed and my account seemed fine. When I went back to my laptop and refreshed my browsers all was well.
