Let me tell all of you the changes of the SWINE battle net.Now the GameSpy of SWINE looks shut,but it has been changed.You need 

go to ‘C:\WINDOWS\System32\drivers\etc’and see this data ‘host’.Open ‘host’as same as the txt files.And you will see this 

in the txt:
# Copyright © 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

127.0.0.1       localhost
::1             localhost

Add these words under the line of the words of ‘::1             localhost’，

65.112.87.187      peerchat.gamespy.com
65.112.87.186      master.gamespy.com   
65.112.87.186      master0.gamespy.com

And now it's ok.
