这是ABAQUS6.4第二章中的例题，当我做到Job步时出了问题，提示如下：

ABAQUS Error: The executable G:\ABAQUS\6.4-PR11\exec\pre.exe
aborted with system error code 29539.
Please check the .dat, .msg, and .sta files for error messages if the files
exist. If there are no error messages and you cannot resolve the problem,
please run the command "abaqus job=support information=all" to report and
save your system information. Use the same command to run ABAQUS that you
used when the problem occurred. Please contact your local ABAQUS support
office and send them the input file, the file support.log which you just
created, the executable name, and the error code.
ABAQUS/Analysis exited with errors，请高手帮忙分析一下是什么问题。
