My computer crashed and rebuilt to an earlier registry. I had just updated to IE 6.0 service pack before the crash. I can't tell for sure whether it reverted back to IE 5.0 or not. I tried downloading the update again,but it won't work now. Now I can't sign into any of my Hotmail accounts. I'm getting the "Page not found or DNS error" message. I've tried the troubleshooting listed on that page. I did notice this: "Some sites require 128-bit connection security. Click the Help menu and then click About Internet Explorer to determine what strength security you have installed." When I click on "About IE" it reads: "Cipher Stength 0 bit" Is this the problem? How do I change to 128 bit connection security? This is driving me crazy. Any help is appreciated.
