在Windows 7计算机上运行Ruby 1.8.7，Rails 3.0.7 - 在周末尝试升级到Ruby 1.9.2，但遇到了问题，因此已经回到了1.8.7。在恢复我的应用程序并重新安装所有gem之后，应用程序最终使用rails s：
启动=> Booting WEBrick
=> Rails 3.0.7 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
[2011-08-15 14:05:28] INFO WEBrick 1.3.1
[2011-08-15 14:05:28] INFO ruby 1.8.7 (2011-02-18) [i386-mingw32]
[2011-08-15 14:05:28] INFO WEBrick::HTTPServer#start: pid=3692 port=3000
但我无法访问该网站。浏览器只是坐在那里“等待本地主机......”并且完全没有来自rails的输出。我对如何调查此问题或可能导致问题的原因感到茫然？据我所知，MySQL正在运行。事实上，我甚至可以通过'rails console'成功启动和使用控制台，但WEBrick拒绝向我发送任何页面。那里有任何我应该看的原木吗？或者有人知道可能导致这样的行为吗？
我遇到的唯一错误是当我关闭服务器时，所以我不知道它们是否相关，但这是我收到的：
`[2011-08-15 13:59:24] ERROR Errno::ECONNABORTED: An established connection was aborted by the software in your host machine.

找不到任何其他内容甚至调查。唯一可能让我担心的是，我确实做了一个Windows Update，并在周末进行[尝试]升级的过程中选择了十几个新的Windows补丁，难以想象会导致这种情况吗？
其他环境信息（据我所知，自升级之前没有任何变化）：
