求助求助 安装ABAQUS时出现问题

我的电脑是W7 32位的系统，安装之后运行时出现Cannot connect to license server system.
The license server manager (lmgrd) has not been started yet,
the wrong port@host or license file is being used, or the
port or hostname in the license file has been changed.
Feature: cae
Server name: 10.10.143.194
License path: 27011@WIN-20101209OYZ;
FLEXnet Licensing error:-15,10. System Error: 10061 "WinSock: Connection refuse
d"
For further information, refer to the FLEXnet Licensing documentation,
or contact your local Abaqus representative.
Abaqus Error: Abaqus/CAE Kernel exited with an error.
一直打不开，这是什么原因啊？
