遇安装问题，请帮忙

各位好！

      我在一台机上安装POWERPCB5.0，装完后用出现以下文字，只能运行在试用模式下，非常急，请各位帮忙解决一下，谢谢了。

      Security system wasn't properly initialized: The lookup for the hostname on the SERVER line in the licese file failed. This often happens when NIS or DNSS or the hosts file is incorrect. Workaround: Use IP-Address(e.g., 123.456.789.123) instead of hostname

怎么没有帮忙呀?急死我了！等着用。各位有知道的，顶一下吧！

licese.dat文件不对，按解文件做
