Just a few hours ago I was happily surfing the web using IE7B2preview and then all of a sudden I started getting the "Internet Explorer cannot display the webpage" page at every webpage. I rebooted and tried again, still getting the same error, I downloaded IE7B2 and installed it and got the same problem. This even happens when I try to access a location on my hard drive, and FireFox works fine. I've tried reinstalling, clearing the temporary internet files, the cookies, the history, the form data, the passwords, I've tried spyware scanning, and virus scanning, and still nothing.
