Fixed the connection error (301): 1) Open up Internet Explorer and you'll probably get a "Poxy Server Isn't Responding" message. 2) If that's the case, go up to "Tools" in the browser tool bar select "Internet Options". 2) In "Internet Options" window that pops up, click the "Connections" tab at the top. 3) Click "LAN Settings" near the bottom of the section. 4) If the "Proxy server" checkbox is marked with a check, click to uncheck it. 5) Click "Ok" to close the "Local Area Network (LAN) Settings" window. 6) Click "Ok" to close the "Internet Options" window 7) Either refresh the page or close and re-open Internet Explorer, it should be working now.
