Microsoft recently made an error in their Windows Defender updates which caused an important
line to be removed from the windows HOSTS file. This line is what is preventing the software from
connecting to the servers in some cases, Vista users in particular.
To add the line back in to the HOSTS file, follow the steps below:
- Browse to Start -> All Programs -> Accessories
- Right click "Notepad" and select "Run as administrator"
- Click "Continue" on the UAC prompt (Windows needs your permission to continue)
or enter your administrator password if requested
- Click File -> Open
- Browse to "C:\Windows\System32\Drivers\etc"
- Change the file filter drop down box from "Text Documents (*.txt)" to "All Files (*.*)"
- Select "hosts" and click "Open"
- Above the line "::1 localhost", add the line "127.0.0.1 localhost" (without the quotes).
- Click File -> Save and then close notepad*
*The original file will look like this:*
/# Copyright (c) 1993-2006 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each # entry
# should be kept on an individual line. The IP address should # be placed in the
# first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one # space.
#
# Additionally, comments (such as these) may be inserted on individual # lines or
# following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x
# client host
::1 localhost /
