error code 529697949，大家有没有遇到的？

ERROR in job messaging system: Error in connection to analysis Error in job after: The executable pre.exe aborted with system error code 529697949. 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=support" 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. 跪求大家给下解决建议
