CST安装问题

最近学习CST软件，下载了个cst2008-sp6版本的，按照按照步骤安装，步骤如下
1.- Install the program. It is necesary to install "License Server",
        but do not install "Dongle Drivers".
        
    2.- Run license manager and stop service. Otherwise the License Server
        will not be patched.

    3.- Run "Main Controller Administration" and start and then stop the setver.
        Otherwise the Controller Server will not be patched.
               
    4.- Copy "license.dat" into "C:\Program files\CST STUDIO SUITE 2008"
        or equivalent.
        
    5.- Edit "license.dat" and replace "server_name" with your computer name.
        
    6.- Copy "cst.studio.suite.v 2008.sp6-patch.exe" into "C:\Archivos de programa\
        CST STUDIO SUITE 2008" or equivalent and run it from this directory.

    7.- Run license manager and start service.
               
    8.- Run CST and choose "C:\Program files\CST STUDIO SUITE 2008\license.dat"
              as license file
为何运行的时候，总是出现错误对话框啊？the lisence key and data for the feature do not match。error code=-8
在两台不同电脑上安装都是出现同样的错误
