FEMAP9.0的nastran不能计算是什么原因？

我电驴上下载了个FEMAP9.0，安装后不能计算，结果文件06、04文件都是0K,不知是安装的问题还是LICENSE 的问题，我是这样安装的，大家看有问题吗？安装了UGNAS.LIC不知是什么意思？
UGS.FEMAP.V9.0.1-MAGNiTUDE:

1) run setup and select the setup type "Network License Server" and
select all options.
2) open the femap.dat and change the "host" to your computer name and
000000000000 to your computer hostid. Run kegen.bat and copy the
license.dat to e.g. C:\FEMAP90.
3) run lmtools.exe in C:\FEMAP90 and manually setup Flexlm services. All
the required files are located in C:\FEMAP90. Start the flexlm server.
4) set the license environment:
LM_LICENSE_FILE = 16323@host (host being your computer name)
5) optionally, you may setup NX Nastran to run independently from Femap.
a) open the ugnas3.lic and change host to your computer name.
b) copy the ugnas3.lic to e.g. C:\FEMAP90\UGFlexlm.
c) manually setup Flexlm services within C:\FEMAP90\UGFlexlm
directory.
d) set the license environment: LM_LICENSE_FILE = 27000@host
6) enjoy another fine MAGNiTUDe-release!
